- ZCZac CaseOct 8, 20254.0I don't mind going to this post office especially since I live so close. I can't say I haven't had my share of problems with them, but it is the post office and sometimes thats to be expected. Generally when I go I'm in and out as opposed to other larger ones. I wish parking was better, but downtown Clayton is pretty small
- HMHatem MoustafaJun 30, 20231.0Very bad service
- ADAz DumaroJun 3, 20195.0Not all post offices are open on Saturdays, this one I believe is. So when I needed to send a package on a Saturday this post office was my destination, and it was a breeze to do business there. I only saw one person at the counter but he was efficient and friendly. It does help when the line consists of one person. This USPS location seems to be more laid back and less crowded than others. Great one person staff.
