Nicole ,
you are right in the reasonable accomodation, however bear in mind I was simplifying it for the sake of cutting the earlier threads argument short. Meaning the person doesn't have to be hysterical or crying etc.
Point was if the other patrons are impacted negatively, and if the patron who is impacting would be asked to leave IF they were NOT disabled, then, yes they can be asked to either remove the animal, or to be refused service.

I am thrilled to hear that you are blessed by a Service animal, and wish you both many years of mutal benefit and happiness!
