However, in San Francisco, at the poshly filthy Oasis, the audience was unbudgeable, rather snickering, reverent, or judgemental of the quality of Foetus' art. They were there to be amused by outlandish behavior. Foetus couldn't get the gumption to go drink-tossing at the Oasis. He fit in too well with the crowd for that to be entertainment, and damned if he would be taken for a chimpanzee. Rather, he kept his dramatics unmischevious and onstage, symbolically backed by a blank movie screen.
