I once saw a pit boss shut down a low-stakes table because the deck suddenly got extra-favorable. Someone in the group said "wow, look at all the little cards that just came out". And it was true, nothing over a 5 had been dealt to the entire table, and it was a full table in single-deck play, the first deal right after a shuffle. In that situation, I would have put down a huge bet, bigger than I ever would have in any other situation. Unfortunately, I was only watching over the shoulder of another player, and even if I had been playing, I wouldn't have gotten the chance. The pit boss showed up seconds later and said "all right folks, we're closing down this table...".

I wanted to smack the guy for opening his mouth.
