Hey Everyonelooks, I just had similar experience yesterday. At the beer bust I was at the two side trough urinal, the guy across from me picked up his beer bottle, looked at me, and asked, "Can you top me off?" I said, "Sure," took miller bottle and filled it up!
A while later he cruised by the table with an empty bottle, my friend that I had told the experience too, said, "Looks like he needs a refill." I went back over to the restroom, sure enough he is hanging out outside of it, followed me in and had me top him off again.
So another part of this, is that I have started brewing beer, so my friend is telling the guys at the table this, and he says, "and he is brewing a special brew today for that guy," pointing to my piss friend! Everyone got it. It was great seeing the guy drink my piss in public, and having my friends know it!
