Vegans in a hamburger joint

Sitting in a local burger joint last night with the family, one of them posed the question to the waitress

"Which is your favourite cheese in a cheeseburger?"

Imagine my surprise when she replied

"Well it used to be the blue cheese but I don't eat cheese any more because I'm a vegan."

"Excuse me?"

"Oh yes, there are several vegans on the staff here - three in fact, plus one vegetarian."

"Anything to do with the food?"

"Oh no, I just couldn't help feeling sorry for them,"

The animals, I assumed she meant. But apparently management don't like them mentioning that bit.
