I was not there last night, but last two times I played (both within a week) played with that guy. It just sounded like his line w/ 2-pair and the fact that he was agitated for no reason sounded like him too.
The guy I'm thinking of was eager to tell people he has been tipping too much so he was going to track every dollar he tipped into his poker tracker. Since your guy was overtipping, probably not the same guy
