It's a post office. Go to any post office and you have a very similar experience. Generally the people are friendly, though not always. They do seem a little entrenched - most have been there a while. But I find them generally - not always - pretty helpful. And sometimes you can actually walk in there and not wait in line, which is more a function of a suburban post office than this particular one. I think you always have to be ready for anything when you use the USPS. Take a breath people. Be grateful it still exists.
