Bouncers can be such assholes. This guy at a pub that I go to all the time wouldn't let me in today. I showed him three different forms of ID. He just said something like "come back to me in a day".
When one of my friends showed the same bouncer his student ID card, the bouncer asked him what course his was doing and when he said he was doing IT the bouncer wanted to know why the course code on the ID card said "1IF1", not IT. He's a bouncer in Galway. Surely he sees enough IDs from the university here to know that the code isn't the same thing as the name of the course. What a wanker.
