Coupons Refused?

Just got back from Vegas and apparently there is a big forgery thing going on which has prompted some casino/buffets to no longer accept ACG coupons.

How about addressing this? I just bought the new book, and now don't know what is good and not anymore? Thanks!

Hey, jksponge! You didn't mention which coupons that weren't honored. Let us know. I just got back on 12/19/07 and had no problem at EI twice, Santa Fe, Green Valley, Bill's (Old Barbary), Slots of Fun and a few more that I don't recall. I visit family 4-5 times a year and your info will help. Thanks
