The management is rude
Outdated systems (cash registers)
Screwed over on hours (either too few or many, usually too few)
You never know when you will be home
Barely even trained, then you get in trouble for the all the stuff they didn't even train you for, but you learn from it.
Takes a couple months to get comfortable with product locations and departments (but that comes with any store job)
Can't even have water when you're at the register or on the floor, not even for health reasons
Little ability to move upward
The music can make you want to die
Customers become hostile if they think something is on sale and it isn't.
Can become depressing and tedious. I don't recommend getting a job there unless you want to work seasonal.
