Interestingly, in my travels I can only recall coming across that system once, it was at a hotel in Germany and I was quite young, somethiong like 12-15 years old. Now days I recycle at home purely for the environment, but I don't think I cared much back then - whereas, with a vending machine that paid out when you returned a glass bottle, young me was very pleased to be able to do that, to help pay for the next bottle.
