Here's an idea I had. You ask to see someone in the marketing or promotions department (or whatever) and tell them you are considering having a big group come to their casino in the next month or two. To generate interest, you want to buy some chips and take them back with you, and give one to each person you plan on inviting....but it obviously can't be ANY dirty used chip, but a brand NEW one.
I'll bet that the marketing person offers to sell you as many new ones as you need. They think you're bringing a whole group...I'm sure they'll LOVE to help. Plus, the guys at the door will hold it open for you on your way out.
Just an idea....sneaky, but it might work.
