From Springwise.com comes a pointer to POINTWC, a privately run public washroom in Paris. For 1 EUR, Springwise reports that:
Customers are welcomed by smartly dressed bathroom attendants, who also sell items in the boutique WC’s boutique shop. Impulse buys vary from diapers to designer toilet-paper holders. Needless to say, the bathrooms look (and smell) impeccable, and are cleaned after every single use. Women are provided with a powder room — a ’21st century boudoir’ — which offers hotel-sized toiletries, ample mirrors and good lighting.
