Today’s invention is a way to encourage people to wash their hands after using public toilets.
There are often just as many sinks as toilet cubicles, so why not site one sink inside each cubicle?
A user closes the cubicle door and if, when they open it again, they have not run the tap for at least 30 seconds, a light switches on over the door -together with a loud message of admonition ‘Washing your hands helps protect everyone’s health, bozo.’
(Ok, maybe not the last part, but you get my drift).
