“It has never failed that I go humbly into our Post Office with an unusual problem and throw myself on the mercy of their counter. It can be James or any of the staff that reassure me they've got this, and they do. Cheerfully, without making me feel like the inadequate customer I feel I am! I have always loved the postal workers, I especially love my Millstadt ones! Thank you! Merry Christmas!Penny Jestes”
“Really helpful staff. Also; good to support usps. Awesome mission serving all of USA.
Edit: yikes. Lots of Karen’s and Kevin’s in these reviews. Maybe don’t vote for people actively defunding the post office and they won’t be so stressed out to help y’all.”
