Long ago in public toilets for women they sold tampons and sanitary towels in a small vending machine, discreetly tucked away in a corner. The one I saw yesterday was the first thing to greet you at the entrance, and offered more options.

As well as the above, they also had two types of condoms, breath mints and headache tablets, which takes care of most sexual situations, ranging from “I hope so” to “Yes” to “Can’t” to “I have a headache”.

Really though, they might consider having babies’ nappies in there too, because that would complete the picture properly.

It would serve both as a practicality and a warning. I am surprised no one has cashed in on this, to my knowledge.
