One that just happened tonight...
Playing $10 spread limit locally. Room is small (six tables) and has three games going, ours being the largest. A 50ish guy had been playing awful LAGtard earlier on our table and lost a rack. He left and came back hours later to play in the smaller $6 spread limit gamealso going on. He had clearly hit the bar a time or three in his absence.
Guy leaves for a break and stumbles out of the room. When he returns he ambles over to our game, looks at the seven seat which was next to his when he was in our game but is now occupied by a woman who is herself on break. He starts freaking out and loudly saying"Wheres my chips?! What is this my chips are gone!?!"
Guy is starting to come unglued when the dealer at his game calls over "your chips are here sir - seat three!" Guy looks hella confused and then realizes he went to the wrong table and stumbles back to his own game. As he does a young smartass at our game calls out "have another drink!" to which the guy waves him off and yells "Shut the hell up!" He gets a warning from floor and continues playing.
I thought of it after the fact but I could have been a real douche by saying "Well sir, your $10 spread chips are dispersed here, here and in my stack"
