Qwest Field – home of the NFL’s Seattle Seahawks – often brags about having the league’s loudest fans (so loud they recently created a seismic tremor), but they sure don’t treat them right!

Check out the video below, which shows that a large beer and a small beer at Qwest Field are actually the same size!

Update: Qwest responds: We weren’t ripping off fans who bought large beers, we were giving extra to fans who ordered small beers.
