What’s everyone’s opinion? I’ve always been brought up to wait my turn and would always wait for the person in front to finish. I had a right prat in Lidl today who started to load their shopping on the belt before I’d barely unloaded my full trolley of shopping on to the belt. This left me with a 1/4 of the belt so took longer and all I got back from him was “you don’t want to mess with me” when I said he should have waited.
