On a similar front I saw something brilliant last week in our local supermarket. a rather elderly woman was at the check next to me and had decided to follow the governments initiative on trying to reduce excess packaging on produce. Before putting anything into her bags she removed ALL excess packaging at the checkout .So the multipacks of biscuits had all the outer cellophane discarded, as did the fruit/veg which had been put in bags - I am sure you get the picture. It was a wonderfully chaotic scene. The poor woman on the till just sat there in a kind of agreeable bemusement but the supervisor who came across was very peed off at the mess and said as much to the old woman. The reply she got was great - "well if you wish, I can leave and shop elsewhere. Of course you will have to bag all this back up again". The supervisor ( a very officious type of person) promptly left. Delightful.
