evidence: Never turn down your receipt — unless you don’t want a Chick-fil-A free sandwich, that is. Chick-fil-A gives away a free Original Chicken Sandwich when you fill out a survey using the link on the bottom of some receipts. About one in every five receipts will have the survey on it, so always keep an eye out. [...] Through the Chick-fil-A app, you’ll receive coupons randomly throughout the year for discounted or free food items. In the past, we’ve seen free breakfast sandwiches (regularly $3.89), free chicken sandwiches (priced at $5.59), and free nuggets (normally $5.39) all given through the app. Unfortunately, these coupons are regional, so it’ll depend on each individual owner to dispense the coupons. [...] Usually if you’re one of the first 100 people in line at a grand opening, you’ll qualify for a free Chick-fil-A Chicken Sandwich meal a week for an entire year (worth $431.08). Temporarily, due to health and safety concerns, new restaurants are instead awarding this prize to 100 Community Heroes impacting the community. Keep an eye on the Chicken Wire to keep track of future openings, and like your local Chick-fil-A on Facebook to keep track of recipients.
