Chock it up to my less-than-abiding attitude toward people (just ask <br/>the author of this post, she'll tell you), but I have never found myself in customer service.<br/><br/>I did, however, have about an eight-year run in janitorial arts. <br/><br/>As humbling as I'm sure it is to bow your head and tell the ass hat across the register that yes, he did order his steak medium, not medium well, and that even though he finished it with palpable enthusiasm before speaking up, he is spot-on when he says you don't deserve a tip, try cleaning up the mess he makes when he gets back to his office bathroom. <br/><br/>There is nothing, nothing that brings you closer to (or pushes you further from) the Lord like having a sweaty fat man emerge from the men's room only to tell you that the can is overflowing.
