My least favourite:
"Passengers are reminded to always (sic) use the handrail and not to run on the stairs" I think it goes, or rather went, because the last few times I have used the stairs down to Glasgow Queen Street low level the incredibly irritating continuously looped announcement has been replaced by a loud hum and a few crackles.
Can't say I noticed droves of people running and falling on the stairs due to the lack of fatuous advice though.
While I do agree, the problem lies in when people put in claims as they were not warned there are any stairs and what to do. People are moronic sometimes. We need more Judge Judys' in this country!
