Never, unless in a hospital or severely ill. Never could understand the point of that - once I've hit the bathroom and brushed my teeth (both of which I do immediately after awakening) I might as well sit at a table. Less chance of a massive mess.
I was once an accomplice. I was the "lookout" and got a candy bar for the job, but I was only 7. Somehow, the candy bar just wasn't as sweet as it should have been. Tasted like bad conscience. Because crime doesn't pay.
