And yet it is the same day, same action. Thanks a lot. There is no cure, except to avoid glutinous grains the rest of your life. I do not eat out very much because everything contains wheat, but if I do I usually call ahead to the owner or manager. I recommend this.
Most restaurants are willing to accommodate their customers with food allergies.
My mother once purchased some prepared food at a certain kosher delicatessen. I do not remember why, but she decided to return it for a refund. She was very upset that the manager put it back in the display case to sell to someone else. This was not a packaged food, but something which might well have been on our dishes. Although it is proper to give people the benefit of the doubt, but that pizza shop was supervised by a rabbi, and not by the customers or managers.
