I know they're a bunch of simpering lettuces but surely even the HSE
can't think that confused passengers is a health and safety issue??

IIRC there was a problem on the Central Line (92 stock has door open and
close buttons) where people were pressing the close button which caused
the doors to close on following passengers and (allegedly) injure them.
I don't know whether in those circumstances the warning note is sounded,
but on 92 stock the doors start to move before the warning sounds, which
isn't helpful. I haven't noticed that it's a problem with NR stock
where door close buttons are provided.
