(38,347 posts)is based on the general rule ADA for accommodations. It predates the specific regulations implementing the ADA with respect to service animals.
Even so, the example given is consistent with the regulations I quoted to you: Generally, this is not likely to occur in restaurants, hotels, retail stores, theaters, concert halls, and sports facilities. But when it does, for example, when a dog barks during a movie, the animal can be excluded.
In other words there are a few rare exceptions, not "a wide variety of conditions." Specifically two exceptions, and the example falls within the exception that the "animal is out of control and the animal´s handler does not take effective action to control it."
As for links, I gave you the citation to the regulation which I quoted. Let me google that for you Rule 36.302
