Who's going to save the world from tough steaks, overcooked legumes and surly service? Why, it's consumer crusader, that's who! You may have dined with this penny pinching superhero who takes such umbrage at the quality, quantity or presentation of their meal that they leave the restaurateur little choice but to waive all or part of the bill. Consumer crusaders never view their table tantrums as a cheesy ploy to duck the bill. On the contrary, they consider their public display of dissatisfaction a valiant blow for consumer advocacy, even if it leaves you red-faced with embarrassment.
