I don't normally swear, but what is the fucking problem here?
People not eating nuts = some people have to forfeit nuts for a short while, they manage
People eat nuts as they're selfish bastards = possibility of death
Yes there are other allergies, but nut allergies are very common, more likely to be airborne and normally more serious.
Are people really saying that they couldn't eat nuts for a few hours? IMO there are much bigger issues than someone not being able to eat nuts on a flight. If not being able to eat nuts for a short time distresses you that much, you need to rethink your priorities.
Yes, the woman in this terribly sad story took a known risk and was not in a plane, but on a plane the risk is amplified as there is no hospital nearby. The plane has to emergency land. Massive cost is incurred. People are delayed. Possible death.
In the scheme of that, can you see how not eating nuts for a few hours is the better option?
