Areal GF poser here. This just happened to me tonight and I wondered what the consensus on her would be . Let me just state that I think I got it wrong. On reflection I would have done something different.
Situation is I walk into a casino and put my name down for poker. 20 minutes later my name get called. At the time I am playing the slots so I cash out and go and find my seat at poker. I place my chips in front of me and go off to get cash for my coins. I get back and sit down and start playing poker. First hand because I'm a new player I have to ante up. I then fold the cards. Second hand I get a hand worth playing and end up all in and win the hand. Just as I collect all the chips someone asks me why I am sitting in their seat and where are his chips. I say these are mine I just put them here and awas certain they were mine. Turns out I had an RiS moment and sat at the wrong table and played 2 hands with someone else's chips.
What happens next and what should I have done?
