Enter this code in the designated field and follow the prompts. If your receipt lacks a survey code, input the store number, visit date, and time instead. Answer the survey questions honestly to provide valuable feedback about your experience. Once completed, you may receive a validation code for special discounts or free menu items on your next visit.
