When I was a Security guard at a resort condo there were many times that I could not get people to exit the hot tubs at closing time until I started rushing in and saying loudly that the pollution alarm had just gone off and that meant that someone had peed in the hot tub water. It got arguments and accusations started among the guests but they all got out of the hot tub quickly. I never said that it was the normal condition of the hot tubs that there was “pollution” in the water.
