Playing a tournament on Ladbrokes, get AA on the button but the dogs really need to go out and are whining by the door.
UTG raises for half my stack so I click the raise-any box and go out with the dogs. I get back in to find that I'm sitting out (as expected) but that I have the number of chips I started with... checking the logs, someone else has moved in before me, thus negating my ability to raise and removing those little check-boxes

Turns out UTG's KK beats MP's QQ without improvement.
not big money but it didn't make me happy.
