I went to collect an online order. There was no assistant at the till so I waited a little while. I then spotted an assistant stacking shelves so I went over to her to ask if anyone was serving and she looked really annoyed. She came over to the till and then shouted to another assistant who I had not spotted who was also stacking shelves that there were people waiting to be served who also came to the till and then she asked where was the queue and then said there was only one waiting, as if it didn't matter that we were not being served. This is not the first time assistants have been abrupt in this store. Very poor customer service.
