How are we suppose to support this store??? The staff has got nasty attitudes and no willingness to serve clients!!

Yesterday I actually convinced my husband so that we can buy groceries from Checkers in Secunda(He does not like the store). We bought R10 000 worth of groceries and at the till Khethiwe (The cashier) and her packer did not even acknowledge us as the clients standing in front of them. It came to a point where I asked here please attend to the client in front of you instead of talking to her all the time. Then I was told we do not have mini's. No explanation, no nothing just a finger pointing to a poster saying no mini's. Then I asked a lady standing at the counter who did not even answer me just drew up her shoulders. The checker liquor next door was so smelly I could not breath and when I told them the shop stinks they said oh its the pipe's. How are we even suppose to support these stores!!! I am very upset and I wasted my time and money and was treated very poor by staff!!!!
