Customer service at checkers differs by race

I went to checkers in N1 mall yesterday after work and my feet were killing me because of the type of shoes I was wearing, so when I got there it was around about 18:30, so I great this young packer, you must see the way she looked at me and I asked her Haybo cc why do you look at me like that and she said to me it’s the way I look at people, then I said to her can you please fetch me bread because I’m not fami**** with the shop and I’m tired but I need bread and bear in mind the shop is empty and they’re just standing around and chitchatting, she just showed me directions on where is the bread and they just started to laugh about it and in my mind I’m like could that be a white customer she would have been running.. her name is Ziyanda.
