Head outside and steal a car to drive to Roman's cab office, shown on the map as the 'R'. Drive into the marker to start the mission.
Drive Roman to the hardware store and follow the on screen instructions. Once Roman gets back in the car ignore the initial GPS route on your map and quickly drive straight ahead and turn right then immediately right again. Now follow the route on the map back to the cab office. As long as you immediately go straight ahead the loan sharks' car will have to turn around to follow you, giving you time to get a comfortable lead.
Once you get back to the cab office you will complete this mission and open up the first set of random character missions. These various 'friends' appear at specific places on the map as blue icons. Some of them only appear at certain times, which makes them tricky to complete, but with a few exceptions, as explained later, they must all be completed for the full 100% completion rating.
