In Venezuela, there is this beer ad that features a Ms. Fanservice known as "la catira Regional" ("the Regional blonde", for the brand of the beer), that's always in a bikinior somerevealing outfit. But everybody is more concerned about why she never shows her face: would she be ugly? Would she be a man...? And, not happy with making the whole country be worried about this matter, after years of teasing they make this, where you can see her face very briefly for some seconds. Isn't it cruel?
