Terrible. Mail is delivered at 6:00 to 7:00 pm when regular carrier is on vacation or off. Cannot believe can't get mail delivered during business hours. This is why I use FedEx more and more...hope someday FedEx put USPS out of business. Deplorable service.


The postal carrier that delivered mail today 6/9/2017 @ 125pm to 125 Windsor Drive was by far the most RUDE POSTAL CARRIER EVER.....He is not one of our normal carriers, who ARE ALWAYS amazing people! I HANDED HIM A BATCH of outgoing mail as he was walking past our suite and he gave me the rudest stink eye and then asked me if I had some sort of problem. I said no, do you?. He then said no, I am asking you....so I replied, no but now I am asking you. and he just kept walking....I am blown away at the fact that this individual is allowed to talk to people this way....he is elderly and obviously very miserable and should not be allowed to speak to people who do absolutely nothing to him in that way....
