I've given my grandmother rides to a senior citizen club a couple times, and EVERY SINGLE TIME she SLAMS the door behind her. She must think since she'* old and not as strong she has to slam it to make sure it closes or something, but it really pisses me off.
Other things include playing with the seat controls, only not switching it to passenger seats first so they f*** up my seat when I'm driving! My brother isn't used to luxury so he doesn't get that you have to move the switch to the right to move HIS seat.
Other things that I don't like are when people I don't know touch my car, especially when it'* clean. I don't mind if someone I know rests against the door or fender (unless they have any buttons or metal objects than can scratch it of course) but if someone ever sat on my hood I would flip out!!
One other things is someone else washing and/or waxing my car, ESPECIALLY the dealership after an oil change. I specify NOT to wash my car because they use a brush on it which scratches the paint. One time they STILL washed it after I asked not to.
They almost did it last month, I would have
if they did.
