Arola is an Asian supremacist and a shithead racist Filipino asshole. He is also a fat, glutton who smokes pot continuously while on air with Dietrich. I have seen many like him in bars. The fucker will scout-out a group of white men and ambush them.
I have been in quite a few bar fights where "bouncers" of his "ilk" just want to fight. And assholes like Arola are normally hired to "spot" and check ID's.
Arola has a similar "anger" as Dietrich that is displaced and irrational. It is prevalent in all of these assholes. Vinny Barbarcik is just along for the ride as "Peter Moon".
It's all fiction with Moon.
