I went to the Dexter Post Office for the last time today. I’ve have lived in Dexter since 1990. When Todd began working at Dexter, he was friendly. He has gotten progressively rude. I cut him some slack because of COVID but I am tired of him snapping at me every time I walk in and I might not be doing the right thing. It is just as easy to be nice. Perhaps he is unhappy but we all need to be a little kinder right now. Each time I leave the Dexter Post office I feel as though I have been slapped in the face. Thank you for letting me vent. I find that the Hamburg Post Office is much more cordial.


I sent a letter on 1/20/ She has not received it. Why? 7550 Grand Avenue48130
