Who is The Zen Master from Tales of Ordinary Madness and what is their importance?

The Zen Master is an older Asian man, who performs Roy and Hollis' wedding ceremony. He is described as patient, spiritual, and very thin with translucent ears. After the ceremony, the master spends time socializing with the guests, but he leaves quickly once Bukowski demands that the Zen Master hand over his ears. The Zen Master subdues Bukowski as gently as possible, but evetually ends up throwing him into a cactus plant.
