This whole thread reminds me of a bizarre incident in 2009, involving a manager at the place I worked at then. My place of employment was in Glenrothes, and I was sent to Glenrothes with Thornton station, to pick him up from a train, which had came from Dunfermline Queen Margaret.
I had got there, to find the train had gone, but my manager wasn't there. He phoned me to tell me, he had been unable to get off the train, and had to carry on to the next station, Kirkcaldy, before getting a train back to Glenrothes with Thornton. What happened was, on the journey from Queen Margaret, when the train got to Glenrothes with Thornton, none of the doors would open, then the guard buzzed the driver to leave.
My manager did complain, and he showed me their reply, which had to be read to be believed. They basically said that, as few people leave the train in the morning (this was about 10am) at Glenrothes with Thornton, and as there was nobody wanting to board, the guard simply decided not to open the doors, and buzzed the train to leave. They also said to my manager that he should've informed the guard as they reached the station that he wanted off, as the guard didn't know anyone did.
Given the fact my manager bought a ticket from the guard four stops beforehand, that last point amazed me.
