I really was not looking forwards to going to the post office to pick up a letter for signature. My experience has always been aggravating at post offices, with long lines and impatient people, and mean employees.
To my surprise there was no one in line when I showed up at 3pm on a Thursday. There were two people behind the desk, and I got quick help from a really friendly postman. The other attendant next door was also making friendly conversation with the lady next to me.
It was a very nice experience, and I would definitely use that location again soon.
