. Talia was a salesperson, newly hired by Ed's Electronics Shop. On Talia's first day on the job, she was left in charge of the store while the manager and the other salespeople went to lunch. They specifically told her not to sell anything over $50 but to just tell the customer to come back in an hour when they would have returned. While they were at lunch, a customer came in and decided to purchase a new stereo TV set and several accessories. The total sales price was $1600, and the customer couldn't wait. Talia sold the customer the merchandise at a $400 discount. When the customer returned the next day to pick up the goods, the manager refused to go through with the deal.

Explain the manager's legal obligations in these circumstances
