Well, I think the only solution is to get rid of the cheesy burritos and sour cream. If we standardise it to vegan burritos then no-one will get confused!
A couple of times I've let vollies get away with putting out vegan mayo, and I promise it will never, ever happen again. It should never be out.
Shannon's right, it's economically indifferent, if not cheaper, to have vegan burritos.
