Yes I think I have seen her become embroiled in issues with Northern, in which neither her nor the staff came across in a good light.Is it the lady who has Northern scared stiff so they let her travel regardless? I'm assuming she had to travel on Virgin today for whatever reason?
They would have probably boarded unnoticed, but if the TM had decided that she didn't want the customer on her train purely because of the previous incident then it is also possible she may have seen her if she had been able-bodied and made the same refusal of carriage.Most likely, as someone else pointed out upthread, the able-bodied person would have boarded unnoticed and only have been seen once on the way to Chester. So there is a material practical difference in how they would have been dealt with, which is discrimination.
But if the company has not banned her from travelling, and if that is the reason given by the TM, it would be a totally invalid one that would surely lead to disciplinary action; I do not see how a TM could decide to effectively ban someone from a train due to a previous complaint if the company did not impose any such ban.
Yes if the aim was to maximise exposure, then don't move away from the train, ensure a lengthy delay, keep arguing, don't compromise...This is certainly the pragmatic line for an "average" passenger, just like "always accept a PF even if inappropriate and then appeal it". However, if you're a disability rights campaigner...
