As a Swiss guy, I must say I only see this in rural areas. It wouldn't work in big cities like Geneva I think (too many people living in urban areas who don't respect our wonderful country and that's a shame).
In Geneva thirty years ago there were newspapers for sale on the street using this system.
My father told me that when he served for our national army back then, soldiers just left their weapons alone in front of the train station while they were having a coffee before going into the train.
