It shifts the risk of slow business onto the employees (servers) since the business is able to shift the lack of revenue onto them. One could argue it also shifts the reward when business is booming. However, that's not 100% fair. Because the business is willing over seat tables and sell food even if they don't have enough servers or kitchen staff to keep up. This results in a poor experience which means servers are working hectically and often reduces their tips (as a percentage per table).
