One of my hobbies is autograph collecting. When I lived at my old place, my mailman would carefully place my envelopes inside my front door, and the rest of my mail in my mailbox. He always earned his holiday tip from me.
At my new place, I've had two postal carriers over the past six years. This current guy seems to watch out for my envelopes now, too, although I no longer have a front storm door on my new house. However, I got home from the office later than usual the other night, around 6:30, and for some reason, the carrier happened to be pulling up on my block to deliver a package to my neighbors next door. As he drove past my house, he leaned out of the truck and yelled, "Hey buddy, you got TWO today!!" There is no reason why, out of his entire route, he would remember how many large envelopes I received on that particular day, being that he didn't know he'd be seeing me later that night. Now that is service! He, too, has earned his tip.
