The Burn Scam was used to get the Leverage Team out of the Pierson Aviation building in "The Nigerian Job".
Premise
The scam uses the basic human reaction to a physical handicap and/or disfigurement, and exploits the moment to secure the objective. The Burn Scam is more of a grifting technique than an actual scam.
Application
Nathan Ford calls this "Plan G". When the team cannot exit from the roof (as planned), the team makes a quick change in the elevator, and Parker plays the role of a disfigured woman. Both Alec Hardison and Eliot Spencer escort her and then exploit the guard's reaction, so the three thieves can make an uninterrupted exit through the main doors.
