I had just moved back to St. Louis in December 1995 and was back at my old job (Ass't. Customer Service Mgr. at Venture). A customer wanted to return an item because it was defective, and wanted another one. Unfortunately, we were all out, and wouldn't have them in until 3 days later. He didn't like it when my rep told him this, so I went up there to tell him the same thing. His response: "Boy, they must have scraped the bottom of the barrel to find you."
Well, I decided to have some fun with him. I said, "Well, I could call another store, but I'll pass," and walked away. Suddenly, the guy is like, "Aw, come on! I didn't mean it!" I was like, "Well, I don't know. I mean, I'm the bottom of the barrel, remember?"
The guy starts begging and pleading, telling me that he wants to give the item as a gift to his wife for Xmas (which is 5 days away). I give this "in thought" look, and say, "Okay, lemme see what I can do."
Found another one at the next closest store. Guy is happy; he apologizes profusely. I grin profusely, but graciously accept.
Those are the rare moments when I like to wield power as an awesome weapon.
