Best post office in Leicester, Massachusetts (MA) 2024

I live between three different post offices and this time I chose to go to the Leicester one. I went there to drop off a first class package but I had it packaged up in a priority mail envelope (Didn't know this was an issue, but now I do). The lady named "Becky" totally freaked out. She said I couldn't have the priority mail packaging with a first class return label. She then went on and criticized the way I taped the package. I told her I could have taken the package back and re-did it. She insisted on doing it herself, so she rips open the package, tape comes off along with the label, causing the label to rip. This was such a terrible experience and I will not be going there again. I hope Becky does not work there anymore! ~Mitchell
