best thing ive seen is the pee bowser in one of the towns up north. its driven by a special constable on a friday and saturday night, who was a local business man ****ed off with his shop and others being used as a lavatory. when someone gets caught doing it thye have a choice of an 80 fine or to let them call the pee bowser. he turns up and gives them the necessary brush and bucket of water to clean it all up. apparantly people are so ashamed when they get caught that the problem has virtually been eradicated.
