Are you mocking my black belt in blackjack? I think Sensei Snyder would like to have a word with you. So would Billy Blanks and his aerobic back up gang.
I'm pretty sure we were trying to make light of a serious question. But yes, always be alert and careful.
I never carry my entire bankroll with me. If I need more, I go to an atm. But usually, if I lose the amount that I'm carrying with me, I'm in no mood to play anymore. If I make significant winnings, I am aware of my surroundings and proceed with caution. Is anyone watching my every move? I would believe that all Advantage players do this anyway since they are trying to gauge the “heat” in the area. So it should be natural to be cautious with a lot of money. I try not to park far away from the casino. I go with friends on these sessions, etc. If I'm forced to walk through a vulnerable area, I ready myself for anything.
