i constantly used to use terms like "post-haste" followed with "RESPLENDENT!" when a servile pleb was at my beck and call.
also, back when almost all tollbooths were staffed by a "human," i would do thus: i would wait until the thing would be prepared to hand me my change, then just stare at it wide-eyed and bewildered. i would then say, with very deliberate enunciation and at raised tone and volume, "EXCUSE ME, BUT I WOULD LIKE A GLASS OF MILK." nobody ever gave me any.
