JC Penney review: service in the men's shoe section

On Sunday 2/16/2020 I went to the store to purchase a pair of penny loafers for my son. I asked the floor rep for help and he asked the other rep what kind of shoe I was asking for. She replied, " No we don't have any." Looking over in the next aisle I locate the penny loafers and I show them the shoes for further reference, in case someone else asks. The male clerk resonds to me, "My bad?" I could not believe I was in a JC Penny store. My bad? Are we on the streets? I requested a managerLatisha who later appeared, I advised her of the situation and she said she would speak to them regarding the altercation.
Spending money in an establishment and being treated in such a manner is bad business and very unprofessional.
