The post office was very busy yesterday, 12/10/2020. The line extended through the vestibule into the side room with the lockboxes yet the line moved quickly. I had an international package and had not completed the required documents. Angela patiently assisted me and was professional and kind. So often we don't take time to compliment people but are eager to complain. This post office is effcient and has some of the nicest employees. Thank you and Merry Christmas.


This must be DeJoy's plot. You have to pay to ask a question. I live at 952 N. Brys in Grosse Pointe Woods. We haven't had a regular postal carrier in a long time, but our usual sub is Aaron, and we love him. I asked him yesterday if he's going to be our regular carrier, and he looked disappointed. He's applied, but someone with more seniority got the route. She's out sick, so we haven't even met her yet. Please, please, all the neighbors want Aaron. Can we please keep him? Thank you!
