After reading all of the responses, I can see that most of us innkeepers are nuts. It came down to about 50/50 on telling people about the nuts. I put a sign out just to be safe. By the way, I made the Grand Mariner French Toast recipe posted on this site and 12 out of 12 guests told me I should make it again. Thanks.
Score!
The more I have thought of this the more I think posting was best - doesn't take but a minute! Today's labels all contain a note if the substance contains or is processed in plants that also process certain (listed) highly allergic substances like nuts. In restaurants there are now notes (tiny print) when items contain nuts ...
We talk about those with allergies that do not mention it to us... some things are more obvious in breakfast foods than others and they just do not think of such at breakfast. A similar example: We took our daughter to a upscale burger joint the other night, each ordering a different style burger & fries. Little did we know the fries would come with paprika sprinkled all over the top and on the plate. She is very allergic to paprika, can't even touch it. We had to send the entire thing back explaining that they could not try to salvage the burger to serve her or she would spend the night in the ER. Usually when she eats out she asks if paprika is in the dish - burger & fries one of the exceptions but not any more!!!
