Kill Your Speed......

Yesterday afternoon at work was quite boring.
There seemed to be very little customer flow at my window. There were plenty of people running through my station to get to the mainline station down the road though.
This is where the trouble/fun started.
I started using my barcode scanner on people who were running. I'd point the scanner at them and "trace" them as they ran past my window.
Not that funny in itself I know, but, several people were actually stupid enough to stop running and say sorry. When these people saw me laughing at them, they called me a "Cheeky Chappy" and continued running.
Actually, come to think of it, most of them called me an "Idiot".
