Thanks to some very "Smart" MLB fans in Oakland we can now see how we are all getting scammed on beer at the ballpark. It's $5 for a small beer and $8 for a large and the two equal the same amount. It's not only happening in Oakland, there are also videos from Toronto and even in Seattle at a NFL game.
My suggestion is if you are buying beer at a professional game it's probably cheaper to go with two small beers and save some cash! Check out the proof below.
