These are two beer cups from the counter, we drank the beer and filled it with water for this test. One is the 4.99 "Small" Domestic, the other is the 8 dollar "Large" Domestic.
See the difference for yourself. In other words, you're paying $3.01 more for what is basically the SAME AMOUNT OF BEER!
This was filmed in the A's Coliseum after an A's Rangers game. Photo after the jump.
