maybe she makes decent cash working that shift or like someone else said maybe she stays at home with her child during the day.
additionally, there does seem to be some stigma related to working as a waitress and i am guilty of it myself, even though i waitress as a part-time 2nd job. i always seem to want to clarify for customers i meet that i only waitress for fun and for extra cash and that i actually have a college degree and a "real job". i dont know why i feel compelled to let people know that possibly im worried they might not think as much of me if i was purely a waitress at a sports bar?
