For an example, he wanted some headphones. Now, the headphones have one kind of jack, but the room has two kinds. I stuck the adaptor on (so it wouldn't matter which kind he needed) and handed them over. He smarms back here a few minutes later, leans waaaaaaaaaaay over the desk, bitches at me, "I didn't need THIS," and hands me the adaptor. That's nice, honey, but could you get out of my FACE!? Honestly, it's not like I gave him the adaptor to piss him off. Why does he have to act like I did?
Damn, see if I try to anticipate customer needs again.
