When I’m eating out, I have to immediately move the salt and pepper, ad tents and other miscellaneous clutter out of the middle of the table and off to the side or up on the window sill. I also find myself stacking all the litter at the end of the table so the waittress can take it away easily. I like a clean space when out to eat - and so I can reach across the table and hold hands with my SO without issue.
People at traffic lights that stop their cars 50 feet behind the one in front of them. Why don’t you just pull all the way up? You’re going to have to cover that ground anyway.
I don’t know why this gets me, but it does.
Preach it! I’m the same way. I just don’t get it. Are they afraid of being rear-ended? Every time I get behind one of those, I have to quell my strong compulsion to honk at them, or carefully creep up until I’m inches from their bumper (I never do the latter, since it’s not safe if I get rear-ended, but I occasionally do the former).
And woe betide them if they stick me at a light! Especially if they gun it at the last second and squeak through the yellow.
That’s not funny. My boyfriend does that to me, instead of just telling me something’s in my teeth or on my face. It drives me nuts!
Use a really obnoxious-looking typeface. Ideally Kidprint or Playbill. About 144 point. And make sure your stickers are dayglo hot pink or lime green. 
I’ve been a passenger with someone who did this! When I pointed it out, he said it would give him an out in case of a carjacking. The guy was loony in other ways as well.
