A man's gotta eat
A man's gotta eat is what you mutter when you're getting screwed over for money or you're stuck at a job that pays less than a pizza delivery guy.
My boss said, 'A man's gotta eat,' when he cut my hours again.
My coworker said it when he got a raise of $1.
I told my friend, 'A man's gotta eat,' after he tried to charge me $50 for a burger.
