Just accept it, OP. All the posters who weren’t there, didn’t read your post properly and have never met you know better than you do, OK? You whined and you argued and you are a boomer and you probably put cats in wheely bins or something.
Being sensible for a moment, I have seen some aggressive behaviour by train conductors. Usually directed at quiet, polite people.
I was on a train to Newcastle and two Japanese girls got on at York. They had bought tickets from a machine and hadn’t realised that cross country tickets weren’t valid on Transpennine services. Why would they?
The conductor was really aggressive with them, immediately: just as the OP describes. It was really uncomfortable to watch; it was obviously an innocent mistake and the girls’ english wasn’t great, so it must have been intimidating for them.
I and a couple sitting nearby politely intervened to suggest to the conductor that he let them off at Darlington to pick up the next Cross Country train instead of (as he was insisting, much more expensive) their buying two new open singles to Newcastle. No. He wanted those girls punished and threatened to throw me and the other people off the train “if you carry on arguing with me”.
Jobsworth. I bet he had his eyes on his commission. He could have been polite and still taken a hard line, but no. He had to be aggressive. I’m with you, OP.
