Erik Turner, a famous internet personality, hatched an idea to a produce a streaming series based on the stories and events of the staff at a local restaurant he frequented ("Grapes Place"). He met with the group after work one night at Grapes Place and, after consuming a bottle of wine and some appetizers, clearly told them he would pay a thousand dollars to each for the exclusive use of each story if he found it suitable for his website. He continued: "no matter if he used it in any production or not if they agree to forgo any further payments or royalties use of their story." After some chatter amongst the staff, and more drinks into Turner, staff members Kelly, Byner, and Lance accepted his offer by saying "I accept" or "I'll do it" and went home elated at the prospects of fame. Ernie, Jimmy and Dave merely nodded in agreeance and Johnny (the dishwasher) told Jane to accept on his behalf. Jane told Turner that "her and Johnny were 100% in"! Earlier, when Turner had told his partner of this plan, he said, "Don't worry, I don't intend to pay these restaurant folk anything; they'll never do anything about it." The following week Turner filmed interviews with more than twenty of the cooks and servers. The stories turned out not to have much cohesion, and Turner pivoted to concentrate on only one of the stories, that of Byner, whose life story was particularly compelling. Although many of the other staff also had interesting and dynamic tales, Turner concluded that the show needed a single narrative. The show based on Byner's life was a huge success, earning Turner and his partner millions of dollars. Critics and commentators agreed that the show's success was based largely on Byner's compelling life story. None of Grapes Place's staff that interviewed for the show except Byner has received any money from Turner. He paid Byner $1,000 but when the show became a hit, he feared that she might sue for additional compensation. He told her, "We couldn't have done this without your story," and he promised her 1% of the net profit from any use of her story. Byner was grateful and told Turner that he had made it possible for her to stop serving and begin a show-biz career. As it turned out, that "career" was exceedingly short-lived; Byner was a much better waitress than she was a performer. Turner faithfully paid her throughout the show's run. When it finished, he refused, however, to pay her anything derived from the re-airing of the show or from the subsequent motion picture version that he produced. Worried that he will be sued by the staff of Grapes Place, Turner begins eating at Vinny's and soon befriends Brady, another regular customer. As they shared details about their work, Turner offers to sell Brady his complete business for $1,800,000 payable within 30 business days. After agreeing on all terms related to assets, debt, and other matters (including the potential liability from the other restaurant staff), Brady and Turner agree that Brady will immediately go home and write this up and return with a contract. When Brady returned later that evening, he presented the contract to Turner who skimmed it over and signed the last page. Brady could hardly contain his excitement as unseen by Turner was that the actual language indicates that he would only receive $180,000
