Terry, meal comps became more difficult to get when the downtown Boyd properties joined in the B-Connected program. Prior to that, points on your MSS card were not "spendable." You could cash them out, but could not use your card in a restaurant. Hosts wrote discretionary comps, and slot club reps give buffet comps, but these did not come off your points. They were based on your separate "comp account," which was secret -- they would not tell you how it worked.
With B-Connected, you were able to swipe your card in a restaurant and spend your points. And that's what they wanted you to do. They eliminated much of the discretionary comp writing in the process.
