There's a 60 year old guy that's went through my checkout twice now in the past few months - I remember him because he was pretty aggressive towards me, and was so the second time a few days ago. Some people have bad days, yeah, but he's been so rude to me and shouted at me both times for insignificant reasons. My friend said if I get him a third time I should refuse to serve him and get a supervisor over, because you never know, he could be like this to other colleagues. Do you think that would be too extreme?
He plays up that he's "just an old pensioner" if you point out his aggressiveness and rudeness, but (just from looking at him) he isn't physically disabled in any way. Certainly not by the way he was throwing his shopping at the checkout at full force after he yelled at me for not knowing him pointing at his trolley meant that he expected me to unload his trolley -_- He also uses a walking stick as a "prop" in his act.
