Irwin was the manager of Highlights Grill, a sports bar and restaurant. Irwin opened a bank account in Highlights's name, signing the account signature card as "owner." Jody, who was often at Highlights and had free access to its office, told others that she was "an owner" and "a partner." She also opened a bank account in Highlights's name, and signed the account signature card as "owner." Irwin told Kelton, the owner of Natural Cheeses, Inc., that Jody was a member of a partnership that owned Highlights. On this basis, Natural Cheeses delivered its goods to Highlights on credit. In fact, Highlights was owned by a corporation. When the unpaid account totaled more than $10,000, Natural Cheeses filed a suit against Jody to collect. On what basis might Jody be liable for the debt?
