Ok Greater Anglia...
@sally Always good advice, whatever the circumstances!
@sally @cstross can’t have passenger complaints if there are no passengers
@sally that's brilliant. I've love to see that on a plane too 😂
@sally I want to get a job writing those messages! 
@sally We could run a great service if not for those pesky passengers.
@sally I mean, they’re not wrong.
@sally @queerterpreter I suppose the person who posts the travel info would get in some trouble if they said “support striking rail workers, don’t cross the picket lines”
@sally, not so "greater" anymore, is it?
@sally English is not my native language. My interpretation: do not sit on top of the train. So it is probably still OK to sit inside the train.
