When anybody wins consistently a decent amount, say playing 6 nights per week, let's say $1000 per night, watch the demeanour of dealers and manager change. I've seen it both down-under and in the UK. Dealers get jealous, slam down pay-outs, get their noses out of joint. It is a struggle for me to get managers to open the table for me, anybody else, not a problem, because they know from them they should take their money, when I ask, "it is we are short staffed, maybe in an hour".
Expectation? I always without fail expect to win, success breeds confidence, I know I am an exceptional player, I have to be, because I play for a living not recreation. I know I am good because many that have shared tables with have come over afterwards and told me. If I ventured to a casino thinking who knows what might happen, I simply wouldn't go.
Anger, frustration, swearing, cursing and all that is not a problem for me,, part and parcel of any casino environment, because all those emotions do not impact on my bet amount or which side I bet next, you see I can get very rattled, but it has no impact on my bet amount, that is 99% of the time fully in control, I may quit a table, but that has cost me nothing. Maybe you are playing a level that is of no concern to any casino, and don't win often enough, so have no idea what physiological games that take place. I would have to think hard and long if I could be bothered crossing the street for $10 and by the time I decided it would be gone.
