This stuff is not priced to be a reasonable convenience, but to be a better alternative to soiling yourself in public. The most insulting part is paying 2 euros to pee into a smelly urinal and getting a 50 cent discount code for the nearby fast food stand as a courtesy, because I haven't spent enough apparently.
I think the general problem is interesting: how do we price necessities when our ability to pay is so different?
One of the toilets I paid for didn’t even have a seat.
Experienced this a while back in a shopping mall in France. Like, a mall has to be one of the most profitable places in a modern city, pretty sure they can afford to staff a couple washroom staff during business hours while everyone is pouring money into all the mall vendors.
Spoken with the voice of privilege.
