McDonalds and every other fast food chain is essentially dishonest.
Any well informed Vegan should know that they fry their fries in the
same oil as their chicken nuggets and fish sandwiches. Every chain has
been secretive about what ingredients they use in their food, due to
heavy competition from other chains. McDonalds used to fry everything
in a mixture with a beef tallow base. As a vegetarian I don't eat
there and any well informed person wouldn't either. There are many
resources out there about the actions of fast food chains all one has
to do is read it. Vegans and Vegetarians need to make an informed
decision when they eat out. And I feel that she has no ground for a
suit if she was naive enough to think McDonalds just serves plain fries.
