Asda Cafe

After a good experiance in May, I decided to come back to this ASDA café, with gluten free food still offered, however I didn’t expect what was to come.
I picked up my gluten free panini for £3, and they asked about toasting it, they seemed to be rushing a little and not understand about allergies, and I did have to explain, I do feel if they are offering products they should show some more knowledge, and try to avoid cross-​contamination, she didn’t wear gloves, and toasted it outside of the bag, so this could have been what made me very ill, which nearly forced me to leave the City game earlier.
I also ordered a portion of chips, for around 90p, and it was a bit of a kerfuffle to sort them out, they did check the bag, they didn’t offer to show it me, but having had it last time and being fine, I decided to have them, as they told me it said nothing about gluten, and they hadn’t changed the chips since last time. My tastebuds said so otherwise, they tasted different, more like thicker, «chippy» chips and they definitely could have had a gluten coating, or was cooked with gluten containing ingredients, however with the food being so close to each other, they could have been a good chance of contamination.
The staff were not great here (unlike my past visit) and their careless actions with my food, could have been the reason (most likely) of me being very ill after my visit.
My food wasn’t too great, parts of my panini was cold and undercooked, and although it was okay, it was nothing spectacular to warrant the price, and the chips were not fantastic either.
I know this is an ASDA café and I’m not expecting Heston Blumenthal style cuisine, but still they should do much better than this, and have more awareness for how ill someone can be, by eating gluten, and understand that it isn’t just people who are on a «fad diet» who need gluten free, and won’t be ill. ASDA as a company need to do so much more, even the complaints procedure is basically outdated, and goes straight through to the store, when for something like this, head office needs to know!
UPDATE: I did manage to speak to someone at head office, and they give me a ridiculous response, asking for a «doctor’s note» to prove it, when I have never heard about this before, and they was things they done, that could have caused cross-​contamination. I really don’t think ASDA understood about coeliac disease and what it can cause.
