My biggest pet peeve when it rains, the windshield can't get the whole window so there is always a little spot that doesn't get wiped. It's weird but it really bothers me. What is your biggest pet peeve. Another pet peeve of mine is when people double dip especially with a shared dip. I don't double dip with a dip that I don't have to share with anyone. I find double dipping really gross and it bothers me so much when other people do it.
