BAH! I've only done it at the bar when there is a major line!
After just going to the restroom and test-fitting the sink....I can easily see how it would be convenient to relieve yourself while brushing your teeth!
I really liked the argument of peeing in the sink as being a "green alternative". Maybe I can offset my carbon emissions running no cats by peeing in the sink and not using harsh chems to clean? Definitely passing this along!
Last night I was watching the movie "Still Waiting", the sequel to the movie "Waiting" with Dane Cook and the guy from VanWilder and at the beginning the guy is brushing his teeth and takin a piss in the sink at the same time. I thought it was ridiculously ironic that like two hours before I was showing my girlfriend that craigslist post and was saying I've never heard of such a thing. lol
