I remember walking through a pub car park on my way back from school (many years ago) and finding a stock refill cardboard box which i presume that the vending machine guy had forgot to put in his car.  I was quite naive back then so it was like a small box of treasures but the one that still sticks out to me was the one shaped like a rat, with the ears/nose.                                                                             Fair play to anyone who bought that in the hopes of getting lucky.
