h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

We have a notice posted on all our ambulances which says 'Seat Belts Must Be Worn'. Surely it would be better if they were in perfect working order? And anyway, if this is the case, why are new vehicles supplied with brand new seat belts

When a pedestrian crossing says 'Cross Now', am I supposed to get irate, or should I infer that the crossing is annoyed about something?

I know it's been mentioned elsewhere, but there's the classic one about rail crossing in Yorkshire - The signs read "do not cross while red lights are flashing" all very well, but in Yorkshire the word 'while' is interpreted as meaning 'until' You can fill in the rest for yourselves.

Also - there's a sign in central Prague advertising "Non-stop Parking" now work that one out...

There's the following sign on a letter-box outside the Post Office near my house:

'Final collection Monday to Friday 6.30pm

There is a later collection from the sorting office at Fishing Rod Lane at 6.30pm'

Unfortunately, the sorting office is not sufficiently far west to make an appreciable difference in time zone!

"When a pedestrian crossing says 'Cross Now', am I supposed to get irate, or should I infer that the crossing is annoyed about something?"

I would think that only applies to wary Catholics, don't you?
