Just curious, but why is your comfort more important than someone else's? Does your desire for peanuts really rank higher than someone's allergy
to them? Are you really put out by not being able to eat peanuts for a few hours verses their inability to travel without risking anaphylactic shock?
People with life-threatening allergies like to go to places like St. Martin as well.

We can have a reasonable debate on emotional support animals, but sulking over peanuts seems to be a bit on the selfish side...
