My 25 year old attempted to buy beer at the game Thursday night but was turned down. He got his license renewed a few days prior to his 21st birthday so his driver's license is vertical since he was not 21 yet. We have a 24 year old and a 22 year old in our seating group of 8 with the same issue. Apparently an email went out this year to concession workers to not serve anyone a beer who has a vertical license. Who would a complaint about this issue need to go to?
