I don't get it. Why do people act as if they'd die a miserable death if they don't have peanuts on a flight? Is it really that hard to refrain from peanuts for a duration of a flight, even if it means making the flight safer one for a fellow passenger, who has this condition against their will? Is it that hard to be even that considerate for a fellow human being that they need to consume something that could potentially harm someone, and something that they rarely eat when not on a flight?
