My wife and I go to the local casino about once a month. I play BS jackblack, and lose at about the expected rate; my wife plays the slots and loses at about the expected rate (for our casino; no comment).
Almost everytime we are there is a "gentleman" playing - he actually works at the security company at where I work - and we get along like oil and water. He is a true believer of the "sacred flow of the cards", and anyone at third base better play as he would play. His basic play isn't close to BS.
It's gotten to the point where, even if it's the only place available, I won't sit down at the same table he is at, even if it is the only square available.
Last week as I was playing, during the shuffle I left to relieve myself. When I came back, he was at the table. Somewhere during the shoe (4 deck), I didn't play according to his rules (probably hit or doubled down on an A7). He blew up; I responded that "this is the way I play; if you don't like it, there are other tables". Fortunately, he left. (Others on the table did comment on "how rude he was").
Don't really expect a response to this, but it is an opportunity to softly vent about some of the idiots I have to play with.
