Not Having To Pay For Cabs
When you get a regular cab, don't skip the ride, but go through the whole ride. After picking your destination, break the window. When the cab is almost at the destination, shoot out the window. (Make sure that 1) no cops are around and 2) you don't shoot anyone.) He will get out and start freaking out and run. Get out and do what ever you need to do without giving him anything. Viola, you still have your money.
