goatgirl,
I firmly believe on being professional even when confronted with the worst of bad taste or lack of professionalism.
React to it with professionalism and 1) you won't be blamed 2) you'll be respected.
Don't "take revenge" or you'll fall as low as the person who provoked your reaction.
Someone asks you for "burnished oak" tea? Fix a normal tea, and if she/he's not happy, invite her/him to the galley to help her/himself, as you are not able to satisfy her/his demand. And don't forget to use lots of humor.
