What is it with people who come up to you in the street and ask, "Do you happen to know the time?" and then point to their wrists as though to say, "This is roughly where you might find the information I require".
Will those same people point to their crotches when asking, "Do you know where the nearest toilet is?" It's almost as bad as making a phone shape with the hand when asking someone to ring you. What next? Miming the act of typing when asking to send an email?
With a bit of luck, these gestures will go out of fashion just as those 'quotation marks in the air' did, which made the perpetrator look as though they were doing rabbit impressions.
