Barry, a broke but aspiring chef heard that Francis French-Fry, a famous chef, was giving a free demonstration at a local cooking school. Barry went to the demonstration and was impressed with Francis's culinary skills. After the demonstration, Francis and his assistants went through the crowd to answer questions and let audience members know that Francis was giving cooking classes every Sunday morning for the next fourteen weeks for $550. For the next fourteen Sunday mornings, however, Barry showed up at the cooking school and participated in the baking lessons. Due to some administrative mix-up, Barry was not initially charged, but Francis is now seeking payment. What, if anything, will Barry be required to pay for the lessons?
(A) Whatever is determined to be the reasonable value of the cooking lessons.
(B) The full $550, under an implied-in-fact contract theory.
(C) Nothing, because of the mix-up, it was reasonable for Barry to infer a gratuitous intent.
(D) Nothing, because the price of the lessons was over $500 and there was no signed writing memorializing the contract.
