While acting as a fiduciary, you recommended that your client buy a particular brand of refueling station to charge her new, electricity-powered car. You told your client that she would be able to save 70% of the purchase price of the home refueling station through a combination of tax credits and utility rebates. You were correct, and the client achieved these savings. However, you did not tell the client that you were receiving a $200 commission from the manufacturer of that particular refueling station brand. Your client now is furious that you received this commission and never told her about it. Do you owe your client $200?
