    I do think that the postal workers job can be difficult at times and I do believe it is related to annoying customers so with that said, the employees at the Clayton office are exceptionally nice people. Thanks for your support!

    I ship for my business and this post office has NEVER not scanned and promptly shipped my packages. My last post office misplaced packages regularly, so this is a welcome relief and I'm so grateful! Thank You.
