I get annoyed at people who get annoyed at all the above.

Just go with the flow and have a good time. Without all those little nuances, it's not a concert.

PS I'm the dude who is constantly getting beer so until they come up with a better system, deal with it! lol. Keep in mind; I am paying big bucks for those beers so I should have the right away. For every 2 beers, I could be buying an official t-shit instead....

Still a fun topic to read....
