I was playing at this Missouri casino. dd, h17, das, about 55% penetration. Nothing great, but this was heads up and surprising number of high counts came up. I had predetermined to not provide my card. This is MO, where you cannot be barred for counting, but on my last visit at 6d, some calls from pit, and the 80% pen at 6 deck turned to 50%. At one point, I was getting big cash coupons and free room offers even after being identified. The big coupons appeared to be tied to a big loss I took.
After about 2 hours, I was down about $5,000 and about ready to toss in the towel I decided to go ahead and ask new pit boss- did you get my card (even though I had already declined a few times). Almost the next hand, a load of small cards came out, and count turned big positive. Some big wins, then $800 bet, split hands, double down. Within minutes, the $5000 loss turned into $1000 win and pit boss on the phone.
Left without incident. I guess no cash back offers this time. Wish I had decline on the card now, but you never know when how the session will go.
