My fiancé played Pokémon on our date? While we were at the restaraunt?

you are correct, it is rude.... the next time.the moment he pulls it out to play, you should walk out.....when he asks why, tell him....he has no class/no manners......then he can figure out what etiquette is......or get him an etiquette book, and instead of walking out and leaving it up to him, get up, drop the book in front of him, you should not have to say a thing, just walk out and do whatever if you need, get a cab bring cab money or uber money, be sure you have your own keys, just in case you live with him....now he is motivated to read and learn....if left to his own devices, he'd of likely masturbated.......

Sure he wasnt wacking off, I mean thats more sensible.
