Are exposed cards dead?

[TommyO]

I was playing at Canterbury a couple of nights ago and the following happened. Super nice Greek guy sitting next to me bets the river with KT and a board of JQKAx. The next player raises and all fold back to the Greek. He turns his cards over and looks at the board while deciding whether to call the raise. The dealer then grabs his cards and pushes the pot to the raiser. They both had KT and they would have split the pot.

The Greek of course goes ballistic saying he didn't fold. The floor manager agrees with the dealer saying his hand was dead. The Greek then asks the floor manager to review the tape and they still say his hand was dead. Is this right?

The poor bastard proceeded to steam off about $200. I tried to get him to calm down and even suggested we take a walk but he wouldn't listen.
