Presently they give high rollers a small percentage refund on their losses. Instead, they should give back a much higher percentage but only on losses that exceed a high amount. The principle is the same as #73 above. (And there are many other examples.) I contend that both the customer and the casino would like this better as it saves the casino EV (mathematicians have actually exploited the present rebate technique for big money) while doing a better job of ameliorating the pain of those who are feeling it
