Yes, the K-mart in my town had one when they opened the store in the 1970s. I think they removed the cafe some time in 1980s? The store itself closed about 6-8 years ago, sat vacant until about two years ago and was finally torn down.
Remember blue-light specials? They had a little cart with a flashing blue light that they would roll around the store and have short-term unadvertised sale prices on things.
