This is a rather unseemly topic, so let me be the first to mention it.
Some men think it’s all right to stand three feet away from a urinal – for reasons of hygiene, presumably – and hope for the best with their fire hoses. Unfortunately, water pressure can vary and they often leave puddles on the floor, like poorly trained puppies.
This has been a pet peeve (speaking of puppies) of mine since the age of five or so. But on a recent trip to Macau, I found the solution and would like to salute the engineer who came up with it.
You stand on metal studs in a depression cut out of the marble. You do whatever you need to do, including watering your loafers, if you must. Then, when you step away from the fixture, you break an electronic circuit that not only releases water to rinse the wall fixture, but opens small, hidden floodgates behind where your heels were to sluice the floor area with fresh water.
I am deeply impressed... and thanks to the DP2, now you can be, too.
