Alabama monkey
From Service Dog Training

The primary focus of this article is what the monkey can do, but if you look down towards the bottom, you will read about a denial of access case. Now, since these people are from Alabama, I'm going to guess that the candy store incident happened in Alabama. Alabama currently gives public access to trainers from schools, not to owner trainers. The woman with the monkey admits that the animal is not fully trained and won't be for another 3-5 years, thus this is a service animal in training situation. The candy store owner was well within his rights to deny access to this monkey, even in the presence of an ID purchased from a known scam operation (sarcasm). While screaming isn't a good business practice, this owner need not fear the ADA in this case. Service animals in training with an owner/trainer do not get automatic public access in Alabama! This is why it is so important to know your state laws when you are training your dog.
On a side note, the article states "When she goes out with the Huffs, most people are intrigued by Sissy, wanting to touch or play with her. However, federal law prohibits service animals from being touched in public." Ummmm...no? It might be nice if federal law prohibited that, but it doesn't. This is another example of the media leading public sentiment to the side of the animal user, not to the side of the laws.
