Mine is awful. They can have two lines open, but without fail they will only open one at any one time. The queue will usually be going out the door. Sometimes they have one person making the drinks and the other doing the till, but more often then not the same person is doing both.
They seem to only recruit teenage boys without any common sense. The other day I was in there and incredibly was the only person in the queue. Two of them watched me struggle with a buggy and a tray. Another time I ordered a chai latte and the boy who made my drink made a latte and then put the chai powder in.
The cakes have gone downhill too.
