Went to buy doughnuts, I wasn't welcomed properly

Went to buy doughnuts, I wasn't welcomed properly. The cashier by the name of Lucia Mokoena was very rude. I was told that we customer's are a nuisance, she's tired of us customer's. It was as if she's doing me a favour. I mean the one person who's supposed to make our shopping more smoothly and favourably made it so uncomfortable and unbearable. I was in a hurry to leave the store because I felt unwanted and unappreciated. Worst shopping experience ever
