I have Celiac. If I buy something from the super market tagged as "gluten free" I shouldn't have to gamble thinking that whoever's in charge of the packaging though about selling this to fad-chasers. So I decided to instead purchase gluten free products that are actually certified gluten free. That way if I actually get my Celiac acting up I'll have a case to make.
But the idea that one should give up purchasing stuff from super market altogether just because there are companies out there who don't really care about stating the truth about their product is ludicrous. Same goes with takeout. If you advertise your pizza to be "gluten-free" like Dominos used to do with a specific pizza in Australia, I expect to at least find some small letters at the bottom saying something similar to "not really gluten free".
I cannot understand how blatantly lying to your customers can be made acceptable if it has fine print. "Gluten free* pizza! (terms and conditions may apply)" is just that: a lie for which there should be some legal/regulatory consequences.
At all? Or from a professional kitchen advertising gluten free dishes and taking their production seriously because they know it can cause debilitating pain for coeliacs?
