This is the only convenient post office for us; has been since it was built. Clerks always know the cheapest way to ship; can even tell before weighing a package. Few people know anything about return receipt, tracking, certified mail, etc. They explain it thousands of times without belittling customers. I'm one of those people who they wait on, ask me to fill out my return receipt or whatever, and bring it back to the counter. Perhaps since I am always pleasant to them they respond in kind.
