I had $28 worth of food coupons that I purchased at Four Peaks Oktoberfest event. We arrived at 2:30, bought the tickets, and attempted to purchase food at around 3:00, at which time the people in the food tent told us they were out of everything except sauerkraut.

No response after contacting their corporate headquarters.
