Review of McDonald's

I asked if I could see a gluten free menu . The employees response was "we don't have one" I said well are your French fries gluten free? The employee then handed me a packet with all of the food they sell with the calories next to each (which didn't answer my question what so ever!) I then told them that and they said "we can't answer allergy questions" well okay then; how am I supposed to eat? Me guessing your food is okay is not worth me getting sick over.
