I'm not saying people would enjoy doing nothing. It's just sick and a sign of our society's decay where we think the height of the human spirit and purpose is to slave away at a food service job serving food to others who will ultimately suffer for it. Like WalterBright in another reply says, there's probably some small amount of old people who benefit from working these kinds of jobs. The problem is, it's not only old retirees/people working those jobs. But tons of smart, capable people who are forced to do them in order to pay rent to some faceless landlord vacationing in the Bahamas or some shit.
