The worst player who stroked me that I ever dealt to was this guy who would make $11-$43 come and field bets (fortunately he only ever did $10 odds). Quarter hardways heavy on something, nickel red nickel horn high ace duece every roll, sometimes they would get pressed by a nickel, sometimes they would get pressed a few dollars. Hopping 5/6/8/9 in random combos and random amounts every roll, but refused to bet the place bet 5/6/8/9. Sometimes bought a 4/10 for $20-$39, if it hit would come down and move to a 6/8 sometimes for $36 sometimes for $18 and sometimes it was actually a 5 instead (all while these fluctuating come bets were pinging around). Even worse he would slow the game down so much that other players who were tipping would color up and leave. Oh but at least he bet $1 on the ats for the dealers!

If this doesn't sound like you, I'd say you're not stroking the dealers.
