Customers
From Generic Cooking Game Wiki
Customers are an essential part of Generic Cooking Game, where they give you money if you serve them food.
Players are given 450 to 470 seconds (7 1/2 minutes) to serve a customer its requested dish. You can claim a customer's dish by clicking the Claim button, which prevents other players from serving that customer.
Customers will rate the food you serve to them and play either a anime wow sound (if the dish is good) or an angry sound (if the dish is bad), then they will leave an anonymous review.
