Glass bottles have 8 Cent deposit in Germany and plastic bottles/tin cans have 25 Cent. I rarely ever not bring a plastic bottle or can back, but I do let glass bottles stand around near garbage cans for the bottle collectors. I see the same behavior among many others. It's just anecdotal, but that 3x seems to make a huge difference.
