a)Tariq works for an auditor who sent him to a half-day of ethics training where he learned to keep clients' information strictly confidential, to steer clear of conflicts of interest with clients, and to refuse gifts of any value from clients. Lately he has noticed that his boss has joined clients at golf outings at the luxurious DHA golf resort - and that he has not reported any expenses on his expense reports. He has also received an expensive gift from an important client he says is "an old friend." Tariq has never seen his boss report any of this, which is what the company's ethics policies dictate.

Should Tariq do anything about this? If so, what?
