Exactly.
The semaphore usage is a no brainer. Its been a symbol of the "mail stop" forever. Flag semaphore conveying information at a distance by means of visual signals. Its been used in the Pony Express, Trains, Post Office, The Navy etc.
But were talking modern letter carriers not the ones in the 50, 60's and 70's we grew up with that that actually gave a shirt and werent bogged down delivering junk mail and Amazon packages.
