As far as customer service stories go, this is some comedy gold. Our friendly and knowledgable Subway employee found himself making a "Veggie Delight" sandwich for a vegan customer who didn't realize that mayonnaise was NOT vegan, because it has eggs in it. Sometimes the truth hurts, and it sounds like it was a bit of a bummer for this vegan. I mean hey, knowledge is power. You live and you learn.
