Simon Layman is a trust investment officer at a bank in a small affluent town. He enjoys lunching every day with friends at the country club, where his clients have observed him having numerous drinks. Back at work after lunch, he clearly becomes somewhat intoxicated because of his drinking habits and has affected his investment decision-making. His colleagues make a point that Simon handles business with his client in the morning because they distrust his judgment after lunch.

Based on the above scenario, discuss on Simons professional conduct and the impact on his employer and investment industry in general by applying the CFA Standards of Practice Handbook.
