The supervisor/store manager speaks very inappropriately and loves to nitpick and make personal attacks. What they most often say to new assistants is, "Are you stupid? You can't even do this? You have to ask me about this too?" But if you encounter a problem and don't ask them, they will scold you for being "disrespectful." They are inconsistent and keep changing what they say: on one hand, they say newcomers should actively learn and ask questions, but when you actually ask, they only call you stupid and don't really teach you.
They also instill methods of deceiving customers in new employees—so long as money is made, any lie is acceptable. They will stop at nothing.
