I used to bring my wife with me to play poker before our son was born. She would sit next to me. There was no collusion. When she would cooler and stack me the dealers would turn red with laughter.

I also explained not to talk to me or text (anything basically) on her phone while I was in a hand and i would do the same. Because i knew people would see and think whatever they wanted regardless of logic or reason. We still got accused of cheating...repeatedly...

I was prepared for this because I used to get invited to home games with my brother. We were clearly the best 2 players in the game (well clearly to us). Some people would basically have the logic "those brothers are winning...and I'm losing...THEY MUST BE CHEATING!"
