Bad service

I went to spar in mulbarton when I got there the was a long queue which I went at the back of the queue in their deli I waited patiently for my turn to come like everyone else but when I eventually got in front I need to place an order like everyone else but the lady that was helping me was chewing gum to start with and they were talking about what happened over the weekend she couldn't care flying sweet what I was ordering As I was placing my order she walked away had to call her several times eventually what annoined was her talking about me behind my back thinking I'm not hearing her while I could hear after I have responded to her silly remarks she failed to apologise yet continued to make me feel like I was being done a favour to be assisted yet I observed another lady that was helping a white female customer she waited for her to placed an order and responded would that be all mam maybe spar supermarket must tell us that we are not white enough to shop in your stores so we can avoid shopping in your stores I feel like even your staffs are programmed to recognise white supremacy
