I really can't think of anything~

If you don't mind that the boss likes to bully the weak (docks the wages of university student part-timers),

verbally abuses people (you'll be subjected to strings of profanity),

is stingy (makes employees drive back and forth five times just to get the drive-thru price),

likes to pass gas loudly (the boss loves farting in public),

has no respect for personal space (your belongings at your seat often mysteriously disappear or are rummaged through),

going back on their word (what happened to the promised year-end bonus? What happened to the promised raise?),

then your tolerance for being treated like a servant must be off the charts. Welcome to submit your résumé to this company.
