Don't work, I also tried that. My plan was to find someone on line who is cashing in comps for food. They wil be getting 2 dollars or more in comps. I figured ask them to get the chips and you will give them 3-5 each and everyone is a winner. That plan didn't work either. Another is the Riv machines show your comp dollars on the readout. If you are sitting next to someone and you see they have money coming to them ask them to bring back the chips and make the same offer. Barry
