Same here. Sshh...don't tell the peasants our secret! lol
But seriously, over the past few years I can count on one hand the number of basketball games I've missed, so I have seen the gamut of crowd sizes at the dome. I usually get at least two beers and some sort of snack for the games. I've never had to wait more than 5-10 minutes for anything.
Here's some advice for all of you, 5 minutes before tip and the beginning of halftime are not good times to hit the concessions. It's like that at a lot of venues. Basketball has so many stoppages in play during each half that make it super easy to go grab a beer or snack or take a wizz and not miss any action. It isn't that complicated folks.
