Painful questions...
To the unknowledgeable, I just say "look at my past records", assuming you graph results, or "How big is your sample size?", when they ask silly questions based on watching a few hours play.
My response to 'Checks Played !!"
Invariably you lose one or more of these $200, $300 dollar bets and thats when I shout out "Checks Lost !" or "Checks Lost Again !!" to lighten up the situation and shame the dealer into just shutting up...
