Would they be expected to go in to shock in case the peanut allergy person reacted at the other end of the plane?

Luckily, the airline I fly most often has a reasonable policy, being that those in the immediate area of the allergy sufferer are asked not to eat nuts, but the rest of the plane can (and I assume if their seat mate objected, could be re-seated)

If someone were genuinely THAT allergic I don't see how they can function in public spaces (say, the airport, the train to the airport, a hotel restaurant, etc.)
