Poor customer service

I was at Woolies in Vaalmall to pay for two bottles of wines and the que was long and according to my understanding I decided to go to another area to pay and before I could I saw a gentleman working for Woolies and asked him if I can pay for my bottles because before I had paid for a cake, he advised wines aren't allowed to be paid and he decided to assist me to go back and ask one of the tellers to assist. He even went to asked Tumi the controller with a bad attitude to assist me, this lady gave me a bad attitude by telling me I should go back to the que because other customers will complain and that why did I go out of the que, come to my surprise I then joined the que and luckily I saw a friend to pay for me, when I was waiting for a friend to pay, another similar incident like mine happened and a client was assisted to pay for her wines and cake and this customer did not join the que nor Tumi found anything wrong. This lady staff member of Woolies in Vaalmall really need to attend client service training.
