Toilet design says a lot about a culture. In the US public toilet cubicles typically have a quarter inch gap which allows people to see in, although a pissoir, which is a partially open air urinal is almost unknown. The reason for this irony is possibly prudery. The gaps are to prevent impropriety, but the enclosed toilets are because of a general American shyness about toilet matters. A small gap allows monitoring a large one encourages voyeurism. Political correctness due to the fact that pissoirs can normally only be used by men is undoubtedly also part of the reason, although recently funnel based womens pissoirs have been developed.Pissoirs first became widespread in France but exist throughout the world, from Scandinavia to Australia. They fell out of fashion in the late 20th century, but have seen something of a revival, with ultra modern versions being built in places like Berlin. Britain, which shares anglo-saxon prudishness with America has recently relaxed its taboo against open air urinals, due to the problem of binge drinking and subsequent al fresco urination. In the south of England, cylindrical pissoirs which are hidden during the day, telescope out of the ground at night, for the relief of marauding drunken hordes.
