People who can't learn the correct pronounciation of our own players names. My dad being the prime suspect here, apparently we have a striker called Deck-o and a manager called Man-See-nee, pisses me off everytime.
The arriving late and leaving early of the same people each and every week is also annoying.
Having to show my card any time I want to enter or leave my seat in 109, I sit on the back row 3 seats away from the exit, you can actually see me the entire time your stood at the exit checking cards, stop being a fucking jobsworth and let me in/out without interruption, you KNOW I sit here!
Having to sneak a bottle of coke into the ground because the ones inside are:-
A - Overpriced
B - emptied into a plastic container. This also happened for the Bayern game. Now, I can see the reason normally, I do sit within bottle throwing distance of the away fans, however Bayern were on the 3rd tier, I'd need to be Steve Backley to hit the feckers from the lower tier!
Kids who come to the game and spend the entire time playing on their Gameboy/PSP/Whatever the "in" thing is these days. If you're going to bring your child to the match then make them watch the match, otherwise leave them at home, this isn't a creche!
Families who attend 1 game a season, in the FA/Carling Cup, sit in front of me in block 109/110, and then look disgusted that people might just use foul language and/or raise their voice at a football match. This isn't panto, assess the situation and, if Timmy and Billy's little ears can't be allowed to hear the things grown men say in an adult situation then leave them at home.
The fact that the tannoy system seems to have been turned off in the East Stand, no matter what the announcement, whether it be the pre-match team, the substitutions during the game, or the half time activities, I've no idea whats being said.
The fact that, for some inexplicable reason, the floor of my row seems to have a constant covering of oil or some other stunningly slippy substance. The stewards had to cover about 30 metres of floor with cardboard boxes for the Stoke game as it was simply dangerous. I'm on the back row of the lower tier too, so the floor/seats aren't even subject to the elements. My guess is some form of cleaning machine is stored there and leaks!
The idiocy of opposition fans who use the "Where were you when you were shit" song, especially those living in the most fragile of glass structures (Newcastle, I'm talking to you here). Anyone with an iota of knowledge about football history knows City fans were, in the main, HERE when we were shit.
The above is in no way an exhaustive list. I hate, pretty much, everything.
