@Lustig Andrei,
Well it never stopped me from hanging out at a pool bar. I would just wonder if I saw someone sitting too long if they were using the pool as a toliet. I figure there is so much chemicals in the water I am pretty safe.
Even if the pee is so called sterile - it really doesn't thrill me much to be standing or sitting in pee. And besides as you said it doesn't take long for bacteria to set in - so by the time it hits me, it could be bacteria full.
It is funny how you don't wonder about women doing that - about us women folk. Maybe because you see them getting up so much to use the facilities.
Even so I have been in many a pool bar (more in my 20s and 30s) - not sure why the idea of sitting in water on a stool while drinking alcohol is so appealing, but I have enjoyed it myself.
