Never called for anyone’s job. Said maybe that person isn’t in charge of name plates from now on.
If it was a low paid staffer or an unpaid intern, I’d question why a higher-up isn’t checking their work, esp on stuff that if messed up can reflect poorly on the program.
Low paid workers are a part of most companies and they have a job to do too. I’m the first person that would advocate for raises, but at the same time if you are indifferent about doing things right because you’re low paid, you probably don’t deserve one. I don’t think the parallels you’re drawing apply. I usually tip 20% if the service is decent, but I expect my food to come out right, and if it doesn’t I don’t dismiss it because they’re not paid well.
