Ancient Roman: Excuse me, what is this line for?The ancient Romans in their public bathrooms used to have a sea sponge on a stick that everyone would use to wipe themselves
I recall seeing them in various public restrooms. The theory is fine as the idea was a new/clean area would be there for you to use. The used part was supposed to roll back up into the machine but frequently didn't work so well or got stuck once the roll ended. Personally, I find those air/blow dryer machines just as annoying and seems like they simply move air around and do a terrible job of actually drying your hands. You eventually end up drying your hands on your clothes instead!
Same for many beverage vending machines in Poland in the 1980s. It was considered a breach of etiquette to bring and use your own glass or cup. You were expected to gulp down the drink quickly so the next person could use the machine.I remember those, they were popular in restrooms at gas stations and restaurants for some reason as I recall.
Not as gross, however as soda vending machines in the Soviet Union. I took a College class that spent a week in the U.S.S.R. and the soda vending machines had real glass glasses. Actually, the machine had ONE glass. It had a setup where you "rinsed" the glass, put your money in, got your drink, drank it and put the glass back for the next person to rinse and use. EWWWWWWWWWWWWWW.

There were also vending machines that dispensed drinks in bottles, but they were much more expensive than the communal glass ones.
