Weird, must be the area. I eat out quite a lot and never have run into something like that.
Oh, I have. Last time at a bar on December 26th. This 22 year old knew everything about baseball and was going on about it for 10 minutes or so (we all had empty beer glasses, BTW). Then I mentioned that my favorite Detroit Tiger was Kirk Gibson and she said: " Yeah, Gibson, he was, like, a pitcher, right?".
My friends and I, who had had several beers by then, just fell about laughing and she got really pissy with us. We didn't mean to laugh, but it was impossible not to after her saying she was the biggest Tigers fan of all time.
