Staff are friendly... Just not with customers

Last week (2017/12/29) I went to Builders Warehouse Boksburg to purchase a few things. I got to the till and the cashier (according to my till slip is Philiswa Mkungelo) wasn't friendly at all. I had to force my greeting for her to acknowledge me, because she was having a huge conversation with the other cashier. I had to look on the screen when she was done scanning the products because she was too engrossed in her conversation for her to tell me how much I should pay. Only after I asked who the manager was she decided to put the things I bought into the plastic back. I find this act of unprofessionalism highly ********* because according to my knowledge it was working hours and she was not on lunch. This act of behaviour is very concerning because I had issues with customer service from the same store and I was promised by the managers that I would never experience such customer service again... Yet here I am on Hellopeter again. I therefore request a manager from head office or the regional manager to explain why Builder's showcases such behaviour after I was promised that it wouldn't happen again. Builders... Get your house in order
