Sporadically for a few months, my apartment management had issues with their former mailboxes having had various problems that the carrier(s) had been a stickler about when it came to delivering our mail. During that time, the carrier supervisor, David, patiently took care of my mailings each time I contacted him stating that I had not received my mail that said carrier(s) failed to leave me a note regarding deliveries, and even personally delivered my mail when the carrier didn't do so (so that I didn't have to wait "forever" for it), and also when apt management was less than sprint-y do so so. Just want to give kudos to David the supervisor. And, apt management finally got new better-quality and sturdier mailboxes! (About time...)
