A friend of ours, who has two autistic sons has started a website to draw attention to the laws and needs for service dogs. The website is here.
We've seen first hand how people don't understand the need for the service dog or what the rules are. At Christopher's birthday party last year she had to explain to the manager at DAC Kids why Barkley must be allowed in with the boys.
Unfortunately she had an incident with a McDonald's manager a few months ago who chased her out of the McDonalds and punched her because the manager didn't want the dog in the restaurant. Our friend panicked when one of the boys took off and she dropped a cup of soda when looking for the boy and the manager thought she threw it at her. The manager followed her into the parking lot and hit her.
Video about it here.
