Anthony Ling

 runs a clothing store in Tenpenny Tower. He is a lanky Chinese-American man obsessed with fashion and it is implied that he takes it up the ass like Elton John.

Convincing Anthony Ling to allow Ghouls to live in the tower is one of the options in the quest Tenpenny Tower (quest). He is the most difficult to convince, and requires the highest speech ability(Killing him works just fine to just dont get caught). Buying clothes from him that increase Charisma before speaking with him will improve the likelihood of success. Another way of "convincing" him to let the ghouls into the Tenpenny Tower is to rob his safe and trying to talk to him thereafter.
