We were at Binion's last week. They have a lot of promotions going on. We won $10 in non-negotiable chips and a $10 match play coupon. Tried to bet the chips and coupon on red but where told we could not match the promo chips. So, we bet the promo chips, won and got $10 in real chips. They took our promo chips. I thought we'd get to keep the promo chips. Then we bet the $10 in real chips and the match play coupon on red. Won that and got a total of $30 that we cashed out and left. Is this the way these promos pay out at all casinos?
