Will they?

Will the casino pit bosses and floor persons still be friendly toward you and continuously give you comps if they have you pegged as a card counter? Just wondering what other peoples experiences have been. I usually bet low green to low black and am at the casino twice a week usually squeaking out a decent part time income plus comps. I usually keep my sessions at about 2 hours and wong out at least a couple times after big wins or extended minimum bets.
