Well, once that second kid started believing filling cups with 50 cents worth of cold liquid was worth $20/hr, the movie theater had to find ways to keep their racket profitable. And since they’re already charging an arm and a leg for tickets, any further price increases would leave them with immobile customers or ones who couldn’t carry their own concessions.
So now that kid makes $0/hr instead of $7 he should have been thankful for, and taken as a sign that he should have put more effort into learning while he was in school.
