Eh, no worries. Sometimes it just has to be said.
I had a girlfriend once who would give the waiter a short dissertation about the quality of the food everywhere we went. The first time I was just shocked because it's not like it was bad, but she was telling the guy about it like they advertised 5 star and it was only 4.5. Believe me, we weren't in a place like that.
To be fair, if you've ever done any baking, gluten free is tough to make(edible). But, it's on the menu, so they're on the hook.
haha well they actually ended up not having the gluten free ones and just made regular! I've eaten lots of gluten-free stuff. Haha that's funny about your old gf. I think I'm the opposite of that. It would take me a LOT to even say anything at all.
