"Went with a friend and we wanted to pay for our own items, the man who handed us the bill said if we want to pay individually we can use the app, when we said we want to use card the server said we can work it out ourselves and he stormed off like a child???? No clue what his problem was, then we sat there for several minutes waiting for him to return because he didn't want to wait for us to do a simple sum. Appalling behaviour."
