I've heard of places like that. So sorry you have to suffer through it. Only one LGS here and it is staffed by clueless college kids. Luckily, when they start to say something stupid, I can just cut them off with a quick word of wisdom and they get the hint that they are speaking with someone more educated than them.
Ignorant older blowhards are the worst. They have stumbled through life without gaining the wisdom that sometimes others know more than them and it is a good idea to simply shut up and listen every now and then.
