There has been a lot of conversations about paid parking fees being assessed to customers at several Las Vegas casinos. Some discounts for different levels of loyalty, etc. Well, this is a new approach. The Silver Slipper in Lakeshore, Hancock County, MS now offers a "Valet That Pay$!" promotion whereby customers using the casino's valet service when visiting the casino are given a voucher redeemable for slot play when they pick up their car. What an incentive to come back within the time span described on the coupon.
