List your douchey things you see in public that shouldn't bother you but they do

I'll start:

1) Morbidly obese people doing fatty things (yesterday I saw a woman walking through Wal-Mart with an opened two foot loaf of French bread from the bakery, eating the entire thing like a 6 inch Subway sandwich while shopping).

2) People that wear sunglass indoors or at night.

3) People in quiet-ish public places like bank lobbies or elevators that scream into their cell phones.

4) Seeing cars in a crowded parking lot taking up two spots.

Whatcha got?
