I just remembered another one! At the wee corner shop where we lived, they sold soft drinks in returnable glass bottles. I think the drinks cost about ninepence to buy. When you took the empties back, the shop owner would refund threepence per bottle. The went back to the manufacturer for re-use. He stored the empties in his yard at the back of the shop, and a truck would collect them once a week!
My brothers and their mates, and doubtless all the other lads in the neighbourhood, would sneak down the to the back yard, climb the fence, nick a few empties, then take them back into the shop for a refund! And doubtless it was a never ending cycle! A profitable method of recycling in the 50's, at least for the kids!
Poor man, I don't know if he ever found out, or whether my parents did either. If they had, I'm sure they would have got a roasting! Mmmm. - I must ask my brothers!
