At London Euston station this weekend I noticed a sign at the ticket booths that read "Queue here for tickets for future travel". Which made me ask the question: why would you buy tickets for past travel? Surely all travel is in the future, even if only five minutes in the future.
Well, er, yes – but can you think of better wording? I assume that 'future travel' means travel on any day apart from the current one, only I don't know how to express that concisely and unambiguously on a sign...
