The concessions order should state roof and event timing, delivery window, worker entrance, stand map, food and alcohol limits, required credentials, POS and cash authority, stock owner, water and breaks, and till close. Build the heat plan around outdoor tasks instead of assuming the closed bowl protects everyone from load-in through pack-out.
