When you tell the cashier you cannot have gluten/wheat, they ask if it's all allergy and then they yell it to the cooks so they're aware. They offer you a bowl or a lettuce wrap for your burger instead. They are careful with preparing the burger and I've never had an issue. The fries are safe as fries are the only thing five guys fries! Delicious.
