You are not alone. I have learned what to order and always tell the server that I am allergic to peppers. I eat alot of eggs for protein source so mostly do not have to deal with peppers when ordering. Also don't eat many frozen dinners or prepared soup. What a pain.
I once ordered a veggie omelet and asked for spinach instead of peppers and they put peppers in anyway. I sent it back. And now make it a point to say I am allergic to peppers.
