At work (dealing), floor came over to my table and said, "I don't know what to do. X just had an Ace showing, asked for insurance, people took insurance. He checks for blackjack, nobody home. He finishes dealing the round, flips the hole card and it's a ten. He hits it, gets a 9. Hits again with a 6 and busts. Pays the table then puts the cards in the discard rack then continues dealing as normal. I just turned around and left."
