Disrespectful service

I was at the till point at Pick n Pay in Cresta and the Customer after me moved her trolley right up against me. The cashier didn’t tell her to step back due to the Pandemic Social distancing. But she could tell me to wait. Why couldn’t she tell the other customer to wait because even though I was still busy at the till, this person just started packing her groceries out and kept bumping me with her trolley. The cashier didn’t have the decency to tell the other customer to wait her turn. How ****** of her, because I’m not the same nationality. You need to treat everyone equally no matter the race or creed!
