in these places, it is also illegal to treat a person with a service animal differently than any other person. the person with a service animal cannot be charged extra money, refused service, or kept apart from other people. a service animal can be asked to leave one of these places only if it is out of control (for example, if it is aggressive or urinates inside). the animal has to be on a leash, or controlled by its owner's voice or signals, all the time.
