A new pet peeve (as far as I know... I'm not going to read through 172 pages to see if anyone else brought it up): People in crowds.
I get that it's a lot of people, but you don't have to be assholes. We were at the game on Saturday, and in some areas, there's a bottle-neck. On one side, there's a concession stand that seems to be very popular, and on the other side they're selling something else. But people are crowding around, making a small lane to walk through. We're walking through single-file one way, and people are walking through single-file going the other way. Some dick-cock going the other way wanted to pass someone in front of him, so he walked right in front of the old guy in front of me. He must have been 200 years old. Either that or 55. Maybe 65. It makes him stop, which makes me stop, which makes all the nerds behind me stop. Then some other dick-cock behind me decided he had to pass all the stopped idiots, so he started pushing his way through. Settle down, pee-drinkers.
Or... after the game, we were walking through the tunnel between St John Arena and the ice rink. A couple of fatties (seriously, it wasn't a big stretch to suggest they might have been wider than they were tall) stopped just outside the tunnel to see what there was to see. You take up half the width of the walkway. Keep walking or move over.
