This Achievement can only earn with Franklin
As first you must buy the "Downtown Cab & Co" business for $200.000. You find the Business in the right upper Corner of Los Santos City.
Directly after you buying the Business, you get a phone Call. It is Raul and he introduce himself. This was the first Call from Raul, we need the second Call
for our Achievement.
This may take several real Hours (not Ingame). In this Time, continue the Game, play Mission etc
Normally after 1-3h you get the phone Call. I get my Call immediately after i call Downtown Cab for a Cab, may a mere coincidence or not. You can test it if you want.
Raul says he has a passenger with a extra Mission and ask you if accept to drive him. Push the A Button to Accept
. After this, you have on your Map a new green Symbol "P". Drive to them and pickup the Passenger.
Play the Mission from him and after success you will earn this Achievement. The Mission in your Game can be different from mine in the Video (i have a juwelry Store Robbery)
PS: You dont need a Cab or so for the 2nd Call, drive with your Car and all its fine.
