Today at work I had to do this weird Anti-Money Laundering course where basically I just had to read tips on how to detect money laundering and what to do if I find out a client is laundering money. My favorite tip on how to spot a money launderer was : "Client is quick to volunteer that the money is not being laundered." I laughed at that for the rest of the day. Now I know what not to do if ever I want launder my money.
