Old Ben is right outside the entrance to the New Vegas Strip in Freeside when the Courier first meets him. He warns the player not to go to the gate of the Strip without talking with the Securitron gatekeeper first, or they'll get vaporized. After further questioning, he tells the Courier that he used to be in many jobs, such as a bodyguard, male escort, a gun-for-hire, courier, as well as a butcher.

pcxbox360 If you recruit Santiago and go to the Atomic Wrangler to tell James then go back to Ben and pass the Speech check you will be awarded 50 XP and he will run to the Atomic Wrangler. Then when you go back to the Wrangler you can speak to Ben again to pass the Speech check infinitely. Speaking to James will not bring the option to recruit Ben. You can also still use the black widow perk if you have it. [verified]
