Earlier quoted context omitted.
I am waiting for the day going to the toilet during flight and be faced with a contactless payment terminal to open the door.
After traveling through Europe and seeing the amount of "pay per use" bathrooms, I am torn. On one hand, there are many more public washrooms than in North America, and they are generally much cleaner. On the other hand, paying to basically be a human being feels wrong and I refused to use them. I've used the toilet on a plane maybe 2 times in my life, and I've fly quite a bit, so this probably wouldn't impact me muc…
There are the single purpose ones in the middle of nowhere or train stations, where payment is an attempt against vandalism.
Everywhere else they tend to be free, and contrary to being on a plane, one can search for an alternative.
