Some of these already mentioned.

I also always touch the outside of a plane when boarding.
Definitely, toilet paper over the top.
I don’t have my feet sticking out from the blankets, but the blanket can’t be tucked in so I can’t stick them out if I decide to.

One that drives my wife crazy. In a restaurant or bar, like jckee, I have to sit with my back to the wall. I would rather wait for a table against the wall than take one in the middle of the room. I’ve done it before under extreme spousal pressure, but I never relax the whole time.
