Cleanliness
Let me start off by saying I am a VERY clean person. I take good care of myself. My car is spotless, with absolutely nothing outside of my cup holders. (misc stuff like wallet, keys, and a rag. My room is very clean as well. One thing I really, really, REALLY get annoyed by, is people telling me to clean something.
For example, if i'm going around cleaning something at work. (I work with 4 other people and it's family run) I'll be doing my routine cleaning of the place and I hate when people point stuff out to get cleaned or organized when I haven't even made it to that point yet. They'll just bring me to some random spot and tell me not to forget about it. And it's the most obvious thing that would need to be cleaned, and there is no way somebody like me, who is very detail oriented, would miss it.
God, the amount of times I get called over to move something that just doesn't make sense to move, or clean something so obvious I wouldn't miss it, just annoys tf out of me.
Don't even get me started on when people bring food in my car, leave wrappers lying around, and the worse... spilling sauce or soda/juice in my car.
Wish it was just me in my own clean bubble. I hated being in a BNB with friends because they are so unclean and I was scared I was going to get hit with a cleaning fee.
