If you've ever felt like you over paid for a beer at a sporting event or concert, this story is for you.

Hockey fans in Idaho are angry and are suing an arena management company after discovering that the small & large beer cups hold the same amount of beer in them. The small beers cost $4 & the large beers cost $7, but they both seem to hold 16 oz. of beer, as you can see in this video. 

So, four fans have now sued CenturyLink Arena in Boise, Idaho, home of the Idaho Steelheads hockey team, an NBA development team. Concerts and other events are also held at that facility.

The fans contend that they have been defrauded at all events at the arena, and their complaint could turn into a class action lawsuit.
