As bizarre as your suggestion is, what makes you so sure Thriptic is "high-value"? A guy this volatile and so easy to annoy probably found reasons in the past to justify (in his own mind) 10% tips or lower. Perhaps the cameras (or just a wise restaurant manager) knew Thriptic was in fact a cheapskate that they had little interest in serving.
