One encounter.

This is a reproduction of a conversation I had at yesterday's event. 

Me ( looking at the spread of food, knowing it's Vegan)  "are there nuts in this?

Twentysomething snobby girl ( insert know it all voice)   "It's Vegan"

Me Yes I know it's Vegan, but are there nuts it it? 

Twentysomething {sighing}" it's VE-Gan" ( she was speaking slowly, as if she were explaining to a three year old.)

Me:  "YES, I am aware it's vegan, but vegan food can contain nuts and I am allergic to nuts.  Not just mildly allergic; I am CALL THE FREAKING PARAMEDICS allergic.   I am Call 911 BEFORE I put it in my mouth allergic.  So I REALLY need to know if there are any nuts in this food."

Twentysomething.  "It's vegan"
