I usually try to avoid going near my stand. If I must go, I will walk downwind a ways and dig a depression in the dirt with my boot and go in that and then cover it up with dirt.
Probably doesn't matter though, deer smell piss all day and night and so they are not really concerned, just a natural smell in their surroundings.
I would just as soon not give them ANY clues though because most deer don't drink as much coffee as I do. Sometimes mine smells like fresh brewed.
