Ah, I actually did flip burgers. So I know.
I also did dry cleaning, cleaning service, deli, delivery guy, etc.
Yup I now have enough money to survive without working.
But I also am very low maintenance, thanks to my early life being raised in harsh conditions.
I am not scared to go back flipping burgers again.
"Yup I now have enough money to survive without working" Your opinion is borderline irrelevant then.
