Been there, done that. Don't ask, I was just doing my job.
Uh, folks? Not only are you given a ribbon at the time of the medal award, you can purchase replacements through any Exchange. After a bit of day-to-day wear they kinda get a little grungy depending on where you're working. And you wouldn't want the actual medals dangling off a work uniform.
With a credit card and a total lack of shame one can look like a gen-yoo-wine war hero. Of course, you're in a bit of a bind if anyone should happen to look into the citation, and some of us can get downright testy about that...
Now and then you'll see a medal in a pawn shop. I get a knot in my gut every time I do.
