The Denny's in Green Valley, AZ offers NO AARP discounts

The Denny's at 18875 S I-19 Frontage Rd in Green Valley, AZ, came under new management and has stopped honoring AARP and military discounts.  Green Valley, AZ is a town of over 20,000 full time residents that swells to 40,000 during winter months.  It does not make business sense to me that they would want to alienate that many people who have time for a sit down breakfast during the week.
