Bad service

Service is terrible the self service machine was full so I decided to go to the tills only to find the cashier busy talking to another staff I asked if I can pay she then asked me cash I said no card only for her to send me back to the self service machine and I had to stand in line to use self service machine while she stands talking to her friend I then mentioned to my girl about her service she give me a look and does not take her eyes of me tell I asked her if shes gonna do something which then she removes herself from looking at me
