For most folks, digestion does not get more robust with age; rather the opposite. Were you to visit an Arby’s today, I might advise inspecting their bathroom for operability and tolerable cleanliness before you start eating. Just sayin’
You Good Sir, have an awesome memory. Perhaps we could even say an anal retentive one?
Which is certainly more convenient for you than these folks who 23 years ago had anal retention challenges at the library:
I’m pretty sure imploding is not the risk. Rather the opposite.
With age comes wisdom! If I ever step foot in Arby’s again, I’ll give a cursory inspection first.
I’m to the age where I am listening to me elders more seriously. For example, I’ve now taken to heart this sage advice/credo given by noted scholar, Larry David: “Pee before you leave”. Wise words!
One of the comments in that older thread made mention that most retailers and especially grocery stores did not have public restrooms. So if one was out for a day of erranding and did not intend to visit a restaurant, government buildings were likely the only option. Leading to a training effect.
My theory for the aforementioned Aoki effect (the need to poop in bookstores) has always been that bookstores, among retail establishments, usually have especially nice and accessible restrooms. So if I’m in Barnes and Noble and get the urge to go I’m probably just going to go, but if I’m in Target I’m going to put it off if I possibly can. I’m sure some of that happens on an unconscious level.
You’re far from the first or only person to express a finely graded hierarchy of bathroom preferences. IMO / IME Target is as generically average as public facilities get. Clean enough, quantity enough, and unobjectionable enough.
Traveling as much as I did / do, my standards at least in the so-called First World are pretty indifferent. A not uncommon workday had me pee in 3 different airplanes, 4 different airports, and 2 hotels. Spread across 4 US states and/or nearby countries. Plus the odd squeezed in (or is that squeezed out ) somewhere along the way. Picky won’t work in that environment.
That was my experience as well. When I was broke and hadn’t yet learned how to cook, Arby’s was a good option because they always had some cheap deal like 5 sandwiches for $5. I learned it wasn’t worth it.
There are about 8 billion people on earth. Allowing for the kids and elderly who don’t post their silly life on the internet there are about 6 billion internet users.
Everybody has some foible by the time they’re middle aged. Needing to poop in libraries could still appear in a few internet articles yet have only a thousand “sufferers” world wide.
So 1 in 8 million. That’s plenty close to zero; you won’t find another one in a stall next to you in a library if you poop there three times a day every day for 80 years.
Face it: the OP (the person) is weird. Then again we all are. In something. The OP just picked library pooping and almost all of everybody else picked … something else to be weird about. We’re all fine. We’re just all weird too.
Now I know why my kids had to go to the bathroom in every freaking store we went to.
Thank goodness. I thought they all had weird bathroom fetishes.
Yeah, I Mom-worried that one for, ummm…a few weeks, anyway.
For me, coffee and crapping are cause and effect, 1-to-1. Not every single time, but frequently enough that I depend on it. If I ever have coffee and immediately go into a library or bookstore, I’d bet the house on it.
