Your wish is my command
First and foremost, why would you want a plaque or trophy with a blank sheet of metal? Those things are supposed to have engravings. Otherwise, nobody will know what and who it’s for. If you don’t want your name or position engraved on it, what’s the point?
However, the problem in this picture isn’t the person who requested a blank sheet of metal on their trophy. It’s the engraver who took the person’s words as instructions. Now, this person can forever remember the short memo he left with the engraver that went over the guy’s head. Congratulations on achieving whatever it was you achieved, random person.
