Dollar Tree review: poor management

i am a frequent customer at this paticular location been shopping there for years when the other day i observed a manager being real nasty with a cashier, that cashier rang me up plenty of times and was friendly and social everytime i went threw her line the way that manager belittled that poor girl in front of the entire store was uncalled for i feel as though that cashier would make a better manager then the so called manager who was on that is supposed to be setting a good example for other employees the name on that managers name tag read bess. I feel that the way that so called manager handled that situation was very rude and uncalled for and quite frankly bad for business.
