That's a story from the modern age, RPLondon, and very sad. You appear to have done everything right but the person who did it all wrong, got the seat. Would that person have been as good at opening the emergency door?
I know it won't make any difference but you might want to write to the MD and tell him the same story in the same plain language. They have to realise that they not only did not get their £75 but they seriously annoyed a customer - and that the warning has gone to others. In the recession, a satisfied customer is worth more than £75.
