Yes, there is, in fact, an urban legend involving the state of Michigan and McDonald’s and it’s for the weirdest reason. I was recently made aware that there was once a McDonald’s in Mackinaw City, which was one of three McDonald’s at the time that actually closed for the winter.
In 2021, we had a stainless steel prep table and nobody was within 5 feet of that table, and there was a gallon glass jar of freshly made balsamic vinegarette and out of nowhere the whole table tipped over on its side, and the jar of dressing just flew across and smashed on the floor.
Despite being spelled differently both Mackinac and Mackinaw are pronounced the same. The word's origins go back to the native Anishinaabe people of Michigan.
