Thanks for the replies. Just to be clear at no time have I thought or said that nuts should be banned on board. However having eaten many Danish Pastries, maybe too many looking at my waistline, over the years I have never had an allergic reaction to one. It is an allergy I have had for over 45 years and know the signs well, and for those who may suggest was I sure it was that which caused it, yes I am.
My concern is that the cut and paste answer potentially doesn't take the matter seriously, especially in light of the recent Pret case. A thorough investigation couldn't have taken place in the few days between reporting and receiving the answer, and I seriously doubt if the CC saved it for investigation. Maybe that should be the procedure for the very few cases where this issue may occur.
