So , tell me , what makes you think we should give you a raise ?   I've got several good reasons . I've been here several years , my work has proven to be good , and I've noticed that people in comparable jobs get paid more than I do .   Salaries are confidential , how do you know how much money these " other people " make ?   Well , I've noticed all the new cars around here , for one thing .   Those are company cars provided to the sales staff for their business trips . Also , some employees receive sales commissions . So good salesmen will naturally earn more .
