An updated version of “Kilroy was here”?

Or at least a modern version?
Daughter #2 arrived from Boston today and we went to one of our favorite restaurants, Brick House Grill in Anna, IL, where it's apparently a continuing custom to leave legal tender jammed into the brick wall…

Are there restaurants or other places where you have seen this custom?
