According to an article on Grub
It is extremely important for restaurants and their workers to take notice. Just because one person “with Celiac Disease” may choose not to take care of their health, or doesn’t care about being sick “one night” doesn’t mean that others act that way. Not only is it harmful to our bodies when they don’t pay attention and make a mistake (even if it is an honest one), there may be far-reaching consequences for some people. With Celiac Disease and food allergies, you may not know how harmful something is until it is too late.
Please, stand up and take notice.
