I usually save the frothing for people who I can tell are really interested, but don’t want to join up for some absurd reason. I don’t know why they would lie about their feelings like that, but a bit of shouting and frothing in a corner really gets them agreeable fast. Great technique!

Usually as loudly as possible while wildly gesticulating and showing huge quantities of bloodshot eyeball. Seems effective so far, will continue to report in.
