Mason who has a degree in business administration,

interviewed for two positions, one as a credit

manager for a large bank and the other as a financial

planner. He received a phone call offering him the

credit manager's position, which he accepted. Two

days later he was offered the financial planner's job,

his first choice. He also accepted this position and

then called the bank to say he had changed his mind

about taking the credit manager's position. Has

Mason breached a contract with the bank?
