So you're telling me if you had a food allergy and you go on vacation, you would still go buy groceries and make your own meals?

Yes, there's technically a risk for food allergies whenever you go to a restaurant, but never eating out means you miss out on a lot of life events. The doctor took precautions. They did exactly what they were supposed to. Any restaurant with a sense of food safety knows how important it is to not fuck it up, and clearly Disney skipped out on the food safety training.
