This is true of all restaurants. In fact, I would expect McDonald's to be a beneficiary of this as consumers replace more expensive options with McDonald's.
McDonald's had cheap, fast, and good "quality." Now it is no longer cheap, it is no longer fast, and expecting a burger properly put together will only set you up for disappointment.
In the Bay Area I can get 2x breakfast sandwiches and a large iced coffee for $6.29, taxes included, which is pretty damn cheap. Their Big Macs are regularly 2-for-1 in their app, and accumulate rewards.
I dislike the trend of harvesting all this data using apps, but I also don't really get fast food unless pressed for time.
You’re referring to just offers and rewards right, not an across-the-board special set of app prices?
