I've worked in restaurants for about 7 years.
Restaurants steal your soul. Shift by shift you contract inward, collapsing like a singularity. Soon you'll be only a small, hard, and bitter mote of ego, mocking the world from a point hidden deep within the vacuous husk of a person, repeating over and over to yourself, "this is what I want, I am content".
Only the strong survive. I don't know how many times I've told myself "I'm never coming back to food service ever again". I've successfully stopped smoking cigarettes, but it's restaurants that I can't quit. Either I don't make enough money in a different field or I can't find steady enough work. Fucking restaurants, they're the reason I started smoking in the first place.
The work is always there and the money is good. You can easily find a job anywhere, and you can take it places. Don't like the town you are living in? Leave, there is a job waiting for you in the next one. The hours are good if you want to use your day for activities like skiing, rock climbing, hiking etc. Getting time off to travel or go on short trips is never a problem. I don't know how people work 5 days a week 9-5 without shooting themselves within the first six months. Sleeping on all that money must be comforting at night.
So yes. I have had the "pleasure of waiting tables"
