People eating noisily.
I think someone else has already mentioned this, but I wanted to put in my bit as well.

People make some noises when they eat, that's a given. I'm fine with that. but when they chew with their lips apart so you can hear every little sound amplified? It makes me cringe.

Slurping fluids? If your coffee or soup or whatever is too hot to eat then LET IT COOL DOWN. You're not in danger of starvation, you can wait for a couple of minutes.

Smacking your lips while you eat? For fuck's sake, there is no excuse for that at all. I cracked down on my kids as infants about that one, and they have better table manners than most now.

But the worst of all? Eating while you're on the phone with someone. Ever listened to someone eating an apple over the phone while they talk to you? I've been known to ask people to call me back when they're done, and then simply hang up on them. I don't care that you're calling during your lunch break. Finish your goddam food before you dial me. Otherwise I'm going to take my cell phone with me into the bathroom and take a very noisy shit while holding the phone by the toilet seat, and see how you like that.

Hot drinks taste better when slurped.
I used to sit opposite my boss, and used to drive her nuts by slurping (and dunking biscuits).

Sad truth is: we're really only doing it to annoy you!
