Swiss prostitutes invented a new way to avoid casual encounters with the police. The idea is genius; it is surprising why no one has ever thought about it before. Swiss girls use high-speed roller skates. According to the Swiss police, the number of prostitutes on roller skates is growing fast. It is not ruled out, though, prostitutes in other countries of the world will use the brilliant idea in their practice too. Skate companies will probably launch a special line of roller skates exclusively for prostitutes - in bright colors, outfitted with lights for night rides.
