I just said to my wife the other day after driving 4 hours home. I had to go but stopped at multiple gas stations, and the only one that had a public bathroom was out of order. I told her I don't think it should be illegal to piss outside if that's the only option you have.
In Taiwanese cities you have public bathrooms within a radius of a 10 minutes walk, and they are as clean as hotel bathrooms, and for free. People in Taiwan leave bathrooms clean as they found it, and there is no vandalism in Taiwan. It works if the society is healthy, teenagers and adults of all social classes following common sense of being nice to others and keeping things intact.
During a long car trip I had to find a bathroom at Ballina in NSW, Australia. The facility was a fucking crime against humanity. The urinal had 7 odour cakes in it and still smelled like a aged care home and the toilet looked like somebody murdered the shit fairy in it, cut up the corpse, wore the corpse, then committed suicide with a hand grenade. The whole place was drenched in piss and probably other fluids. It was a fucking disgrace.
A bit unrelated but I remember a drunk conversation with someone working in a had station in Geneva.
The sociological aspect of the gas station is fascinating, within the same minute you can interact with a homeless coming to use the toilet and a guy coming to refill his Lamborghini.
