Bad attitude from fruit section staff

Went to food *****s market The Marc to buy fruit salad and youghut but attitude I got from the 3 laddies who stood there and watched me greeting them no one acknowledged and I even asked to for assistance which a lady by the name of Gugu assisted with stinking attitude and on top of the gave me wrong choice of youghut when I told her that I do not want that one she told what must she do about it, I understand that they must be tired and they have there since morning but that does not give them the right to give us bad attitude to customers,
