The Customer Service provided by the two primary people at the front counter, Kary & Sandy is fantastic. They are efficient, patient, positive and know how to get it done! It's unfortunate they work for a local Post'master' who is a waddling example of why government (quasi) agencies are largely #failIt would be great if this location was updated to include a self-service shipping Kiosk with 24 hour access. In contrast to the value of a kiosk; there is a secondary postal location at a local bank, that is completely redundant, offering no additional value 1/3 of a mile up the road.
