When Lloyd appointed Turlock to manage her gas station-convenience store, she instructed him to require payment for purchases in case or by credit card only. Turlock stopped buying the groceries the store sold from the previous supplier and bought them at a lower price through a corporation he owned. Wiggington, a regular customer, filled her car with gas one day and found she had forgotten her purse. Since she was a weekly customer, Turlock allowed her to give him a signed piece of paper agreeing to pay for the gas the next time she filled-up. Two days later Lloyd stopped at the station to confront Turlock about the purchases from his corporation and discovered the paper signed by Wiggington. Explain Turlock's potential liabilities.
