This is an admittedly tight space for a post office, but I was offended when their lack of adequate traffic control resulted in line confusion and then a decidedly unfriendly response from staff members. I now go elsewhere.
This post office was renovated a few years ago. It's half the size now but more modern. During peak times the line can be out the door. Most of the staff are friendly and helpful. They stock lots of useful things like gift cards which can be convenient.
