The grill it's cooked on also cooks meat patties. Some people do not like any contamination in their food. When I became vegetarian I thought about this a lot but came to the conclusion that if I ever wanted to go out with friends that it's something I'll have to accept. You'd be surprised at the number of places that use chicken broth in otherwise vegetarian fare as well. It's a compromise, but one I'm willing to accept; some people are not.
