Don't tar everyone with the same brush, not all enthusiasts consider themselves to be superior to staff (although as with Ticket Man's example, some obviously do :roll
and think they know more than them, there are some excellent knowledgeable staff around.
Equally I don't think its fair to imply all staff (eg all Northern platform staff - as above) are 'idiots' at that's certainly untrue, yes there are some staff who aren't trained particularly well, but thats mostly the fault of the TOC and certainly doesn't apply to everyone.
