This Post Office,{95446}, is the most useless waste of taxpayer monies I have seen in my life!! The staff is disgusting with arrogant disrespect and appear to thoroughly enjoy hanging around for the opportunity to tell local residents, trying to arrive before they close, that they are closed!! As the staff loiter around inside they stand ready to call guards at the first sign of the outrage they've managed to muster for their entertainment. They go by their own time, not what you see on your phone and they scurry to close the door and turn the key when you approach with cell phone in hand saying "It's 4:56, look!!" The worst part of all this is the smile they get while watching and waiting for your reaction!!!! No "small town charm" in this small N. Ca. tho though less than 1000 residents call this their full time home. Most people would naturally assume a community based, public commodity shared by just about all locals, as most do not have local mail delivery as an option, could and should be a warm friendly place? This post office does not even honer online tracking notices! You package is there when the staff says it is!, got a problem with that!? Its not a question, its what your told. Just remember people, hold your rage until you have walked away, don't let them see it because it is what they want to see!!!
