BAD Horrible service

Poor terrible and Unacceptable SERVICE. I went to fill my car with diesel in the BP Garage Elgin and was attended by a petrol attend who left the pipe in my car for almost 15 min unattended he went and helped another client. Upon return I asked if that is how clients are treated and as for risks of having left that unattended. He clearly said to me there is nothing he can do if there is staff shortage what am I expecting him to do. I told him I wanted a one transaction and change on the litres and he told me he will do his way I explained the reason for payment as I will not make 3 transaction and be financially affected. He just looked at me and proceed with the other transaction which I had to double the transaction.
