    I 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

    Not very helpful staff. Instructions, when asked, are mumbled than being very clear. They assume that you know their postal process.
