Saw this today and have to share.
A good friend is a supervisor at the baseball stadium here in Houston for a company named Ara****, I won't put in the entire name to protect him. He has told me that the profit margin is closer to 30-40% on the majority of the items they sell. And, the workers are paid as little as possible and have to work ridiculous hours from setup to take down. These people also have babysit some of the alcohol drinkers to make sure they are not over served and the company ends up in a law suit.
