Worst delivery person EVER. The post office employee who delivers the mail to the Village of Windsor flat out REFUSES to deliver mail to an entire circle in a subdivision. Instead, six different residential homes have to cross the road and gather their mail. Not only that, but if you don't scrap, and I mean SCRAP the side of the curb clean for 30 feet beyond and 30 feet prior to your mailbox, good luck having it delivered! Plus I have heard that the driver has made other home owners actual RAISE their mailboxes a total of 4, yes 4 inches. Guess this is the prime example why people are delivering less and less mail these days...
