Fast food joints shouldn’t be a place to build a career, they’re a place for students etc to work.
This is why you can’t buy fast food during school hours. Seriously, stop with this bootlicking, boomer classist bullshit myth. All work deserves dignity and a living wage. Aside from that, I will near guarantee that you apply this across the industry, you’ve just closed about 85% of restaurants and hospitality (retail, etc) as most of the people working there are not students. Also, it’s NOT easy work which is another bullshit line. It’s like that old trope about the plumber that comes out and twists one knob and the guy that called them says “you only twisted one knob! Why should I pay you $300?” and the plumber says “because I knew which knob to twist.” Fast food and this type of work is a lot like that, except we don’t pay them well enough for most to stay long enough to know which knob.
Tbh, if fast food employees were paid their worth, there is a decent chance that customer cost would go down because they’d usually be closer to max efficiency and the restaurant would spend less money on things like lawsuits and fines and such because the “manager” had more than 10 minutes of experience and training before promotion.
