i usually go with a set amount of $ that I'm ready to lose no ? asked. treats are already paid for so the way i see it, if i do win some money off the money i plan to lose anyways, i might as well give the casino a chance to get its money back and me a chance to double it ( unless it's some crazy amount that that i didn't have to double). ether way I'm losing money that didn't come out of my pocket if i just use the winnings. might sound loco, but then i've never been right in the head.
