Do you have any idea how much goes into any given food service job. Not only is it customer service, it's usually heavy machinery operation and maintaining, sanitation work, handling of money, awareness of allergens and chemicals and EXACTLY where they are and where they go, intense memory games for menu items and all of their ingredients... You deal with some of the absolute worst rushes doing multiple tasks, you can basically never sit down, most of your cooking equipment is extremely dangerous and can hurt you very badly if you lose focus for any amount of time, you deal with insane temperature fluctuations constantly, food service is always understaffed because it's less expensive to pay you to do the jobs of four people, everyone is incredibly mean to you all the time, and you get paid like absolute fucking shit because people think it's "unskilled" entry level labor anyway.
