unfriendly staff

Today I was at the Eldorado park store.This is my everyday store.I usually buy all my sons clothes from Pep.I was with my son and he wanted to pay for his own sneakers which I allowed as I was there to purchase a few under wear for my mother.After my sons purchase the cashier(Judith) took his payment but did not put his sneakers in a plastic bag.I then followed and paid for my items.After my transaction she proceeded to give me one plastic and placed my sons sneakers in there.I told her that this were two different transaction and that I needed different bags as it was not for the same person.She rudely took out the sneakers and gave me the smallest plastic bag .I was very annoyed and will not shop at Pep any time soon.
