I suppose it was the inevitable result of the Pendroy Outhouse Tour.
This one is in the Azores. It's a coin-operated number. A 10-cent euro piece buys you three minutes, which time-limit is clearly stated on a large sign. In Portuguese. When the three minutes are up, the doors slam shut. The only way out appears to be a red "panic" button, which rings an alarm. Eventually an officer from the police station a block away arrives to let you out. But only if you are lucky enough to have another 10-cent euro piece in your pocket....
