I won't do either, but not because of scent. I doubt the scent is that big of a factor. It's the inconvenience I don't wanna deal with. That's one reason I don't eat or drink in the morning or on stand. Because what goes in must go out.
It works for me 99% of the time.
On a funny note. I had a buddy that dropped his coveralls to crap out of his stand. What he failed to realize was that he crapped right in his coveralls.
He realized it when he pulled them back up around his neck!!

It's a good thing I Don't get texts in the stand. That one would've made me bail out with laughter!![8D]
