Case of several wrongs not making a right.
Gamblers are a superstitious lot, even those of us who know and play the odds. So I understand someone wanting to return to a certain seat or a certain machine even though there is (in most cases) no tactical advantage in doing so.
I'll bet in another thirty seconds your ticket would have been history. My approach, assuming I had done what you did, would have been to cash out immediately, tell the bartender "Thanks for everything," flip a ten-cent tip onto the bartop, and get away from those two yahoos ASAP.
