Family Dollar review: customer service/cashier

I walked in to buy a clear plastic tote, i grabbed other items and put them inside the tote for easier carrying, as i go to pay for the items the cashier informed me i cant do that and said i need to bring tote up front first and get a cart for the items, and proceeds to tell me i looked like i was stealing from her, well first off if this is store policy, then your stores should post signs, second i work hard for my money and im no thief, it was embarrasing cuz she scolded me with a line of customers standing behind me, made me out to look like a thief, this is very rude and poor customer service, will not being going back to this location, 2:15 pm--7/20/2019
