To segment your customer base, like any company that offers "basic" and "premium" versions of basically the same thing. In this case, you get some people who walk in, order whatever is on the menu in front of them, then are maybe slightly annoyed by the price but will take out their wallet anyway. On the other side, you have people who are willing to put in a little effort to find the coupons, and buy the more basic menu items and buy the McChicken instead of the McCrispy Chicken Deluxe.

My dark dirty secret, as someone who frequents fast food restaurants, is that McDonalds is... actually not that bad, even good, and at the least it is very consistent and good value (if you use the deals, sometimes even without) and the people who think it's disgusting are just engaging in a little classism and can go home and watch Super Size Me again.
