No, but I have been stood at a roulette table with a friend who called and won red/black 21 times in a row. He was unamused when I pointed out that had he bet his entire stack every time, rather than the same £10 bet, he'd have walked away having won ~£20M, rather than £210! He lost on the 22nd bet and walked away.
