At one of our conventions about 5-6 years ago, I went to the Hard Rock Casino for the Pink Taco chip. On my way out I stopped a slot machine to play for a few minutes. (I'm not a slot player). Two 25-30 yr olds from Germany stopped at my machine and asked where can We cash these chips. I was far away from cashier and far away from the Rou tables. I looked down and saw 20 Rou. chips in one guy hand. I ashed what he paid for each chip he said 1.00. So I said your have 20.00 worth of chips, and you want to cash. He said yes. I told him I'll save you a trip to cashiers window and gave him 20.00 dollar bill, and he gave me 20 Hard Rock Rou chips, and said thank you and left. A tourist just casually walks away from Rou. table thinking he has to cash in. I have used for traders, and still have 6-7 left. Not really harvesting, just helping out a couple of visitors.
