Same for when you order gluten-free fries in a gluten-free oil vat. There are other vats next to the gluten-free one. I.E. the oil from the non-gluten-free foods are splashing into your gluten-free vat.
Pizza places - I know from talking to my pizza restaurants that yes they do serve gluten-free foods. BUT, pizza is made from flour. In my experience from working at pizza places, I know the flour gets everywhere, on hands, gloves and in the air. So, gluten-free products at pizza joints are NOT gluten-free to me.
this in my opinion and therefore my family will NOT be ordering out or going to any fast food/restaurants anymore. I will not take any chances on making my little girl (now ten) sick anymore. I have been doing very good at keeping her gluten free since we found out she has celiac disease I am not gonna make her sick anymore and have told my relatives and friends house not to do the same with her. I will not outlive my little girl due to someone elses mistakes.
