Sounds good, but it's exactly contrary to how McDonald's operates. At McD's, the goal is to upsell continuously. To transform casual eaters (1x per month or so) to "heavy eaters" who visit on a weekly basis.

A few minutes work at the Googles will show you how this pervasive philosophy started with all of the kids menu items and advertising, and has continued onward with the McCafe and other additions.

The goal is for you to eat three meals a day at McD's. Make no mistake about it.
