"Bring your favorite bottle of wine, and on Wednesdays there's no corkage fee!" "A bar where you can enjoy your favorite cocktail!" "Take advantage of our 'accent wall' plan and get one wall of your apartment painted your favorite color!"
OK now. My favorite bottle of wine may not go with the cuisine offered by a no-corkage-Wednesdays place that advertises on the radio. Hell, my favorite bottle of wine is probably one I can't afford. My favorite cocktail? I dunno, maybe the Cable Car, a variation on the sidecar offered at select Las Vegas Strip establishments? It's not offered at the bar I'm inventing for the sake of argument here, so I guess I'm not welcome. And my favorite color is a hunter or emerald green of some sort, but that's not necessarily the color I'd paint my "accent wall" if I rented a place at the complex I'm inventing for the sake of argument here, so I guess I'm not allowed to opt for my second- or third-favorite color.
Yes, my point is that "favorite" is an ad-speak cliche best avoided in actual writing. What, you think I'm being overly literal? Well, bite me.
But don't actually bite me.
