Indeed. Certainly to me it would be unthinkable to actually begin an argument with another member of staff while at work.Also, the traincrew are between a rock and a hard place. Arguably, "on the day" their job is to run their train safely and on time. It's not their job (if going "by the book") to query why there aren't passengers on the platform.
The correct channels would be to escalate the incident via management (though cold comfort to those unable to board)
The issue is that it has been escalated but without that necessarily producing any long term changes.
At Blackpool North, presumably, rather than Skegness? I don't know, very odd. I've had a manual ticket inspection on arrival before, but in that case we were let out of the side gate i.e. we didn't pass through the automatic ticket gates.Last time I was there, a few months ago, they checked your ticket as you got off the train but they also had the gates working. Why both in the space of a few yards ?
