Last sentence was meant to be humorous, but I failed to identify it as such...
Many years ago I worked at JFK Airport. One night a guy approached me while quickly flipping a badge and saying, "Federal Agent." He wanted to search my carry-on bag so I handed it to him. I spotted his partner standing back in the dark which made that guy stiffen a bit. There was nothing in my bag but a dirty work uniform so the agent gave it back and walked off. I have no idea what agency he worked for or why he tagged me. Maybe they just do training exercises.
A meaningless story but I felt like telling it. :-)
