I'm pretty sure it has been happening at a large airport near you. That's because airports for larger metropolitan areas seem to be continually under reconstruction. For this post, I'm referring to the evolution of the airport terminal.
Not all that many years ago terminals had waiting areas and a few news stands and a limited, "captive" (contracted out to a single supplier) set of restaurants and snack bars. Those restaurants and snack bars seemingly invariably had overpriced goods.
Then cracks in the system appeared. The one that impressed me was the appearance of a McDonald's hamburger stand in the Minneapolis terminal maybe 20 or more years ago. Now, in America, I don't notice any more of those single-contractor operations for food services (news stands still seem to be another story). Better yet, in many airports, the price of a McDonald's burger or a cup of Starbucks coffee is the same as it is off-site.
Behold the contrast with 60 years ago. My example is Seattle-Tacoma International Airport showing old photos found on the Web and a few I took recently.
A few years ago, the central part of the terminal including the main lounge (already re-done a time or two since the photo above was taken), was extensively rebuilt. The photos below indicate the result.
