RUDE & *********** CASHIER

I was at 14th avenue westpack on the 20th December 2018, so after I made a purchase at the till points , I see ' ice cream bowls ' on special for R29.90, then I ask the cashier when is the special ending pointing the ice cream bowls, she said I dont know, and looked away, I said to her you cant say you dont know I mean you work here, then she asked the other guy also working there, " when is YOUR promotion ending"? as if she doesnt work there, the guy also said he doesn't know he will ask someone at the back, ***********! after that the cashier took a promotion paper and look at it snd screamed at me the date, the cashier she refused to give me her name, she was so RUDE, *********** forgetting that without us customers she wouldn't have that job, she doesn't deserve to be there dealing with customers.
