Other allergens like milk, eggs, seafood, etc, don't create an airborne "dust" like nuts do. So they were NEVER a concern for me. How anyone cannot see the difference between nuts and other allergens, just means you're not wanting to think it through. What surprises me really is the jerk attitude about the love of a peanut for that limited amount of time and your entitlement for your comfort over someone's life. Yeah, right, people with allergies should become shut-ins and not have a life so you can continue to eat your snack of choice. Incredibly selfish but doesn't surprise me in today's world.
As to the person who has reactions to perfumes and scents--I'm with you on that one. That is VERY real and getting worse for people. Quite honestly, I can't figure out why people want to douse themselves with some perfume/cologne and then go sit in a sealed compartment for 3 hours. People, you do NOT smell good in that situation.
