I would, and currently do, work for less than the local Chic-Fil-A is hiring for. McDonald’s, Wendy’s, all the big ones around here will pay at $16/hour starting.
However, fast food work is a whole different beast. It is constant and involves hard labor and instant memorization. It requires you to be in the “lunch rush” mindset all day long, because the business model relies on training everyone to do everything so you can run the kitchen with a skeleton crew. It is humbling but demoralizing when dealing with both customers and managers, both of whom assume you are inherently beneath them.
I did my time, about 4 years of fast food. Pretty sure it knocked a decade off my life
