Back in the early 90's I worked with an older gentlemen who was a submariner who told a story about $2 bills. Apparently there were some locals at one port who were constantly complaining about the sailors causing a ruckus, etc.. So to show what a valuable presence the U.S. Navy was, they started paying the sailor exclusively in $2 bills, with the thought being that this would show the local businesses what impact the Navy was having on the local economy. Apparently this was somewhat successful.
