I’m afraid this story has me decided that it’s you that’s weird. What the hell is wrong with reusing plastic? When you show me the data that proves one can get sick from grocery bags, I will stop thinking you’re some kinda neurotic strange-o.
Part of it is the unappetizing nature of using something which most people think of as garbage to wrap food. I’d feel similarly grossed out if it was an unused garbage bag wrapping the food.
I assume that most people would feel grossed out if they had to lick the packaging of their groceries. The carton of eggs might have some spilled yolk, the meat may have some residue on the outside, etc. When those groceries go into the bag, all that gross stuff is now pressed against the plastic of the bag, where likely some of it ends up on the plastic. If you ever use reusable bags at the grocery story, the inside does not stay pristine and clean. It gets stained and gunky from the groceries. I’m pretty sure everyone would find it gross to lick the inside of such a bag. It’s unappetizing to have that gunk pressed against food regardless of whether it’s going to make me sick or not.
I’ll just arrive on scene to say that reusing plastic grocery bags in the way described in the OP is definitely unsanitary and weird. Absolutely. As mentioned before, industrial inks are definitely not meant to be ingested, and it doesn’t take a lot to give you issues. I found out in college that all the oil paint I was casually getting on my skin or maybe getting in my mouth from the brush without a thought could give you a huge range of ailments from losing your sense of smell to coma and cancer. I started washing up properly after that. You don’t want the ink on bags touching your food. And of course, the plastic itself is not food-grade and can leech poisonous chemicals into your food. I’m honestly boggled that anyone would consider this. I also consider plastic grocery bags inherently too dirty, not even mentioning the toxic chemicals. I mean, I put them directly on the floor of my car’s trunk. That is definitely not clean enough to eat off of.
Before they were banned (or discouraged by charging for them) here in CA, we collected the plastic grocery bags we didn’t use to line small garbage cans and brought them to our church, where people apparently wove them together to use as sleeping mats for our unfortunately large homeless community. I never actually saw the output but we delivered lots of bags to this cause.
I had two good ones, but they aren’t acceptable because I’ve mentioned it to my friends. Here they are anyway:
I have a friend who places the empty egg shell back into the egg carton. Yup…cracks the egg into whatever, then nests one half of the shell on the other and places it back in the carton in the recently vacated spot. He says it saves dripping the empty shells across the floor or counter and that the refrigerator dries out the remnant of the white. He says he’s done it for at least thirty years. I have to admit that I’m not sure exactly what is wrong with doing it. (I know someone is going to say that it’s a salmonella hazard or something, but I don’t really see how it is.)
Another friend always orders a soft drink (usually Coca-Cola) with every meal and then stirs it until the carbonations pretty much disappears. He says he likes the flavor, but not the fizz. I’ve seen him stir a drink on and off for ten or fifteen minutes to get it to the point it’s acceptable.
You can usually get away with reheating it once. Reheating it over and over, or leaving it on the heat for long stretches of time, can make it bitter.
It takes a whole lot longer to get moldy in the fridge, however. (Possibly not an issue if your bread has lots of preservatives in it.)
And it doesn’t go stale all that fast if it’s well wrapped.
I don’t think raw wheat is toxic; but I doubt you can digest it, so eating a lot of it might get you no nutrients and cause extra bathroom visits.
Some varieties of raw dry beans, and apparently raw edamame, can be toxic. Raw green beans are perfectly fine (if not contaminated with something.)
I refuse to reuse any bag that held any potentially leaky product. Ones that had held stuff like DVDs or even canned and boxed food can be reused to carry stuff around in - I’d never use them to wrap food in, though.
I’ve read this a few times and still don’t understand. Crack the egg into a bowl or whatever and throw into the sink with a garbage disposal, or if no disposal, set on the counter. You are going to wipe the counter anyway after cooking or whatever, so it seems like a waste of time to put back in the carton.
Putting the egg shells back into the carton doesn’t seem odd to me. That’s the way my parents did it when we were growing up. Don’t know why but they did. I don’t now because I don’t want any shells sticking to a carton I’m going to recycle. They didn’t have to worry about that then.
Our eggshells go into a dish by the sink. When the dish is full, the eggshells are crushed and fed to the chickens.
My eggshells go in the compost, and the egg cartons go back to one of the places I usually buy eggs from (individual farms, farmers’ market, or a couple of the smaller groceries around here will take them and give them back to the farm.)
I’ve had to stop people from putting eggshells back into the cartons; it makes them too grubby to return. It would also make them too grubby to recycle. Of course, some people don’t have any setup available to them which allows returning or recycling their cartons.
Am I supposed to be bothered about being a “neurotic strange-o”? Because I’ve long accepted that’s what am I am. And sorry, I don’t give a rat’s patootie what some faceless stranger who goes around eating out of plastic grocery bags thinks about me. Someone who’d do such a thing is likely prone to lots of crazy-ass beliefs.
Here is something you may not have come across before:
Plastic shopping bags laced with dangerous levels of toxic lead
My mom had the shelves in her linen closet painted light blue “because it keeps the sheets, pillowcases etc. cleaner longer.”
A friend of mine heads a small political club which could be run very informally, but he has elaborate rules, virtually every member of the club has a title of some kind, when he’s heading out of town he formally designates the vice president to be in charge in his absence (and sends out an email to that effect), and, at election time, has a 17-page questionnaire for any candidate seeking the club’s endorsement. Nice guy, but takes it all 'wayyyyyy too seriously.
I don’t have a drawer big enough to put a decent amount of bags in so instead I go all meta and stow to-be-reused plastic bags in a plastic bag. When it gets full I start a second bag and then that gets about a half-dozen in it (more than I’ll ever use in one go) the full one gets taken to the grocery store and stuffed into their recycle bin; the city recycle program here does not accept them for some reason 
Which worked so well with Challenger 
Maybe my life is simpler than yours but I have only four major bills a month to pay. Minor ones (Netflix, Patreon) are on auto-pay and the big ‘uns (utilities, ISP) I pay online but manually. I have a Notepad file (bills.txt) and when I pay the bill I open it up and update it with that month’s number. Come December when it’s time to put in the last ‘12’ I wipe them all, leaving just the bills’ labels and start over again. No paper and I even recycle the file. 
“The starch crystalizes” – whatever the hell that means. I suspect it has something to to with gelatinized gluten or something but haven’t been arsed enough to look up bread chemistry.
I keep my bread in the fridge for this reason. If I leave bread on the counter it will go moldy before I’m done with the loaf. In the fridge I’ve never had a problem. I might get a few stale slices to the end, but it’s better than looking at a sandwich and seeing half a green spot. :eek:
Add a bit of horseradish to that to make what is essentially Big Mac sauce
(some people say add ketchup or that TI dressing by itself is BM sauce,
they are not correct- ya need to add horseradish).
We do, but so so the French and the Belgians and they are the people who actually invented them, though they rarely get the credit, so arguably the OP is the weird one for omitting it. 
I’m a true Dutchwoman, I think chips (US fries) without mayo are a waste of time and prefer them to be drowning in it, as the film rightly has it.
As for the shopping bags, I don’t use them to cover salad, but I do use them to smash up digestive biscuits for a cheesecake base.
Letting grocery bags come in direct contact with naked food is about as unhygienic as eating off a strange table or counter top. The things become contaminated once you put groceries–which have been dropped on the floor and handled by hundreds of hands–in them. People might not get sick by using them like saran wrap, but there’s a reason this is not a common practice.
But I do use them to transport my lunch in.
Somebody way upthread mentioned pancake syrup in the refrigerator: I do that too, (although mine is pure maple syrup), because otherwise it will get moldy.
My ex wife used to wash plastic grocery bags and food ziploc bags along with the dishes. Then she would leave them on cloth drying rope in the garden, flapping in the breeze.
