There used to be 50,000 pay toilets in cities across America until a group of college students in 1970 decided it wasn't fair to have to pay for a natural bodily function and successfully lobbied to get them banned.

Now you can't find public toilets in many US cities and if you want to use a restroom you'll need to use one inside a business that, you guessed it, will require you to be a paying customer.

Capitalism always seems to find a way.
