I've been working as a manager for a fast casual chain for the last few years, working on getting out of that right now but there are some benefits -
Base pay is good plus bonuses at least once a quarter and sometimes every month
Free food during your shift, never have to pack a lunch and free coffee/espresso, definitely helps reduce food expenses
It's a physical job, I average about 7-10 miles a day walking
Probably the biggest benefit, especially since I started looking at FIRE as an option, is the daily reminder of how trapped people are - people come through the drive thru every day in their new cars on the way to work, spend $10-20 a day on breakfast/lunch and god knows how much on dinner EVERY DAY, drive to work where they will sit for 8 hours, spend 1-2 hours sitting in the car on the way home wasting gas in standstill traffic, and probably sit on the couch as soon as they get home - rinse and repeat every day for 40 years and then not have enough money saved up. Half of the people who come in and wait in line look miserable, angry I guess at the fact that everybody else has their lunch between 11 and 1 and decided to eat out too. Seeing that every day just acts as a constant reminder that what I view as a choice many people simply consider mandatory.
