The Surgeon's Lab Coat

The Surgeon's Lab Coat is found on the 2nd floor at Red Racer Factory. You must kill The Surgeon and loot his (or her) corpse. The coat appears to be a unique version of the Vault Lab Uniform. For some reason The Surgeon does not attack you if you wear the Ghoul Mask and you can search her lab without having her shoot rockets at you. You can also use the Ghoul Mask to reverse pickpocket her to get The Surgeon's Lab Coat without killing her.
