overchanged?

So what do you do when the lady at the till in Tesco's gives you an extra fiver with your change?

Well, the answer is:

You look all over the place for her to tell her of her mistake

Not finding her you go back to the huge queue and wait for ten minutes so everyone in front of you can pay with their pennies

You spend further five minutes trying to convey that they have no short-changed you, but that you want to give them money back...

All in all a waste of 20 minutes...

Sometimes it is quite hard trying to do the right thing....
