I saw a post once (might have been on this board) about a young woman who ordered a vegan sub at a sub shop. She asked exactly what was in it, not even trusting the "vegan" label. The guy behind the counter told her all the ingredients and she said yes, she'll have that, with mayo. He said, but you do know that mayo is made with eggs so that's not vegan, right? She got angry and said she wanted the mayo anyway.

Now there's a die-hard vegan for you ... when it suits her purposes.
