Really just depends. They do have ticket people checking at each section who take their jobs a lil too seriously.
Like for example: Checking my ticket upon entering the section, Watching me leave my section to get a beer, making me show the ticket again. I mean i know people come and go but seriously you just saw me leave!?!
I have seen sooooo many people drop drinks and food due to fumbling to show their ticket to the Ticket Nazi's after already being checked once.
In my opinion you got into the arena right? So you must have a ticket? If someone is in my seat i'll let you know (ticket nazi) otherwise just stand there and wait for someone to get you or ask a question. The constant ticket checking is absurd.
After a few beers and on my way to another i walked out and asked "hey can you just remember me?" and did a little jig for em...no dice. Perhaps its just me but they get on my nerves especially when i have my hands full of food and beer and my ticket has already been checked 3-5 times.
