When I was a kid, a ‘Coke’ meant a six-ounce returnable glass bottle. Recently, these 200 ml* returnable glass Coke bottles showed up here. Hard to imagine a kid these days being satisfied with a drink that small, but somebody bought them.
Behind them is a 2-liter bottle, plastic, also returnable, meaning that all three have a deposit paid on them.
Beer bottles half-liter and larger, and wine bottles 1.5 liters and larger, all have deposits and are re-used.
I like that.
