Blackdog doesn't seem to mind doing so, but I personally don't think it sounds healthy.
A scientific poll of the office staff, and a few drug reps and patients, found that 100% of people I saw today agreed that toilets should not, except under extreme circumstances, be considered a source of drinking refreshment.
Apparently, though, this isn't as common a belief as I'd like to think it is.
The city of Chandler, Arizona, has unveiled their new city hall building, which (I SWEAR!) includes signs in the bathrooms specifically telling people NOT TO DRINK FROM THE TOILET!!!
Here's the story. And thank you, Lee, for sending this in.
