Zytech deducts department sales returns and allowances and sales discounts from sales before calculating manager discounts. Mary Dennenberg, manager of the Audio Department, does not think this policy is fair. “1 work hard to train my salesclerks to close their sales, and I work hard on closing my own sales. Why should I be penalized if a customer returns the merchandise?” As the company president, how would you respond to Ms. Dennenberg?
