I've always experienced professional service at the Morro Bay location.


Mailed a card at post office. Was delivered but only a envelope no card or check inside. Envelope looked tattered. Who handles the mail?


Worst Post Office ever... The postmaster Is the rudest guy in the world!! Don't have a problem, Because he sure can't help you!! I put a forwarding in, Half my mail gets forwarded 1/2 doesn't... And now they have my mail, spread across 4 mailboxes..Not sure how this is gonna get fixed... This post master needs to be fired! I'm not the only person that's how the problem with him, Everyone I know has had a problem with him... He definitely should not be an employee of the Post Office... Thank you


The man that works at the front desk, Lee is very unfriendly, unhelpful, and has a condensending attitude. When I returned to the store two minutes after I left to see if I could add 2000$ insurance on my shipment he Responded with a grump face and tone and refused because he would have to go to the back and get it... He's the senior supervisor so what can we do to get someone who wouldn't mind doing his job. " I hope my package doesn't get stolen, Lee!"


Bulk mail acceptance time is wrong on here. The time is 0930 to 1130, mon to fri only since 2011.
