His medical insurance will buy him new knees for his retirement!
Gee, I can instantly tell that your are either an EX postal employee or a current one.
Am I right? Sure I am.
I hate to bust your bubble but “when you were a kid that carrier probably handled 200 pieces a day” is a pathetically stupid statement. That carrier served much larger area than you give him (or the real postmen back then) credit for. You have to remember, that was back when postal employees actually worked for a living.
