Thank you for your article. We used some of your conclusions in our article about Mcdvoice. The mcdvoice.com survey with receipt is an initiative by McDonald's to gather feedback from its customers regarding their recent visits and experiences at various McDonald's outlets. Customers who complete the McDVoice survey are usually rewarded with a coupon code that can be redeemed for a free item or a discount on their next visit. The specifics of the free items can vary, but it often includes items like a free burger or a special discount on a total order as a reward for filling out the Mcdvoice survey.
