We purchased the $8 for $16 coupon & leaving the top half with code intact my wife cut off the very bottom thinking it unnecessary. Without any show concern they refused taking the voucher. The clerk asked manager & he confirmed this decision. The code would tell them everything needed knowing but even after ordering this technicality resulted in her denial & embarrassment. It's sometimes degrading enough using coupons without people using flimsy reasons for denial of their validity. Wouldn't Fatburger love seeing people walk away with nothing after investing this money in their product. I would never again patronize Fatburger at Green Valley Ranch. Reading other reviews I see many reviewers concur with my experience. There are much better hamburgers in the Las Vegas valley.
