Had a conversation with someone today that started with them asking me if I knew what time our local post office closed for lunch. I've never heard of such a thing. To be fair, most of the post offices I've been two have a minimum of two people working the window, so I would understand if a small rural post office needed to close to allow the only employee working a break. But your average post office with two or more windows typically open? Isn't "running to the post office " one of those errands people typically do during lunch breaks?
