pin numbers for credit cards

Now I have seen everything! Out at dinner this evening we paid the bill with a credit card and the waiter said 'sir if you like to give me your pin number I will enter it to save you from coming to the office'. Can you believe it??? On leaving the restaurant we told the owner what had happened and she said 'oh, so many people give the waiters their pin numbers that it is just normal'.

I was so amazed to think that people would entrust their pin numbers to total strangers. T
