My friends like going to fast food restaurants. It's not that I mind, but I'm a vegan, and these restaurants offer few things that I can eat. Even salads contain ingredients like cheese, eggs, and ham. What's more, there may be cream or gelatin in the dressing. Sometimes all I can do is order something to drink, while my friends enjoy their meals. By not offering vegan meals, fast food restaurants are missing out on additional sales.
