No need to call police. The guy should call his friend and bring some money to pay Taxi Pek. At this time, the guy and his friend should video the process and suan Taxi Pek:
"Ah Pek, owe money pay money only, no need like that one. I know you buay song I have a chio gf, but shaming me will not help you get a chio gf. If you really want a chio gf, don't say I never give you good advice, stop driving a taxi. Otherwise, forever you will be watching other people's chio gf from your rear view mirror. Now take the money and go home PCC to the images of my chio gf."
