«City governments are paying local businesses to open up their restrooms to
the public. … The program, called Nette Toilette or Nice Toilet, is active in
210 cities and has been running since 2000. Cities pay from $34 to $112 per
month to a business, and it puts a sticker in its window to tell people that
they can come in and pee for free. … Bremen, a city with a population of over
half a million people, reckons it saves $1 million per year by using the
network, which costs it $168,000 per year. So successful is the scheme that
it has given Bremen the best ratio of public toilets to citizens in Germany.»
