[Sevenfold]

I really really hate this as well. This is my pet peeve.

After losing a big hand, some idiot who didn't invest a penny wants to see my hand out of curiosity.

I now ask him several questions.

"I just lost a lot of money. Why in the heck are you asking to see my cards?"

"What do you think I had anyway? Can you read cards? What is the only possible hand I could have to play the hand that way?"

"If I show you the cards, will the information help you beat me? How are you going to do that? Come on, what do you think I had? You must have an idea since you're so curious."

Then, if I haven't mucked them, which more often then not I'm able to do, I float the cards one at a time over the table (this works much better in a 7 card game like razz or stud) at the player who by now usually has no interest in the hand any more.

If someone says something to me, I say, "I just lost $XXXX! Losing the hand isn't bad enough now this clown wants to see my cards and doesn't even know why!"

I've never been asked twice by the same player.
