Not a nationwide chain yet, but I frequently enjoy inexpensive food and drinks at Whataburger. If you live in range of one and are a senior, you get a free drink with your meal. With that receipt, you can scan it, to take a survey (2 minutes max) to get a free Whataburger coupon with purchase of medium fries and a medium drink. Cost for lunch less than $5.50. Repeat as many times as you like. About 50% off the menu board price. The survey option is open to all, not just seniors.
