The only thing that annoys me with ID is when people take the piss. Normally bouncers and it's happened quite a few times. I hand over my driving license and they'll look at me and it 3 or 4 times, then ask me if it's my brothers, or if I'm sure I'm 18 etc. I get that it's your job but in the queue people have been calling me by the name on the card, I look exactly like the picture on the card, I'm with a bunch of people who are 19 and 20 too, I'm in a student town, on a student night and so on.
There's legitimate suspicion and the point where come on, stop taking the piss.
