I've visited every post office from Auburn Hills to Royal Oak and inbetween and this post office is THE BEST! Easy in and out! FAST and OH MY FRIENDLY service is ALWAYS given! I have NEVER gone to a post office where the employee's ALWAYS have a smile, ALWAYS interact with you on a JOYFUL note and where it is a PLEASURE to visit! I wish they could win some type of award! I give them 10 stars where 5 is given! BRAVO!
