A WELL-DRESSED YOUNG WOMAN having an after-work cocktail at her local pub suddenly hears: "You look great!" She looks around, but sees nobody there. She hears the voice again: "No, really, you look terrific!" She does a 360 on the stool: still not another soul in sight. She hears: "Is that a new blouse or something? Because honestly, you're absolutely glowing!" This time she traces the voice--it's coming from the dish of nuts on the bar.

"Hey!" she calls to the bartender, "what's with the nuts?"

"Oh," he answers, "they're complimentary."
