Another thing I hate about it is that if you deal, they 'play on' to see 'how you would have played'. To rub in how much you could have had.
Complete and utter shit, really. There's absolutely no way, unless you had precisely planned out beforehand the order of boxes you would open for the entire game, that you would have opened the boxes in the same way. Choosing to play on rather than deal would be a different kind of stress, and most likely you'd have played differently.
Everyone on it is also an incredibly superstitious moron.
