Better yet, she's YOUR casino friend...so why don't YOU open up that oh so fat wallet of yours, or maybe open your safe and dole out a few hundred grand to Karen?
She'd really appreciate it and if you have her sign a NDA she'll become your ally and back up your flood of lies about KJ.
For a man about town such as you claim to be it would only be "chump change."
Perhaps you can fly her to LV and turn her out with the rest of your stable: yeah, you come off as a pimp.
