On the 21 November 2020 I went to shoprite at germiston in GOLDENWALK. While I was doing my shopping I was attrack to blackfriday special which wild island it was R10.i decided to take 2 of them. When I got to de till on my surprise it ws R16.99.i told the cashier Nd she called the supervisor she was very moody to me she didn't even wanna understand me, she told me 3 wild island it's R30.i polity told her it's say 10r each. I even took a picture as a prove. For her to b apologetic she jst looked at me. I believe if you working with people you must b happy Nd friendly all time
