Heng Sao Tian Ya
The former part of his arrogance can be forgiven, since he doesn't know their identities (and even if he did, his master would probably be better than the other's status). But the latter part when he tries to bull**** them isn't even funny. He could damage reputation by pretending to understand **** when he really is merely a random butler. I would have him chopped up limb from limb if I as his master finds out.
