poor service

My husband and I went to do our shopping, we were waiting in line as the cashier was assisting in the other clients. As she was done they continued with their conversation and I told the cashier that we want to pay for our groceries so we can leave so she can finish her conversation now and she just said then you can leave. We then requested to see a manager and Dorothy came and listened to her side and the people she was keeping a conversation with then eventually called us aside and asked whats our side and all she did was apologise for the service but need to attend to other things. There was no details taken and confirmation that something will be done about it. Very unhappy with the service and dont feel that I would want to shop there if this is the service we'll be getting.
