Shoprite liquor Kempton Park

I got the worse service from a lady by the name of Sibongile mbele in shoprite liquor Kempton Park, she threw a slip at me and I asked for a plastic, she said why did I say before she closed the till, I did ask for one but she was too busy laughing with other employees and not paying attention on what she was doing, she made me join the que again to get a plastic bag
