Don't get me wrong; I believe the service animal provision of the ADA in Title III is correctly written, should be strongly enforced, and should not be revised, abolished, or curtailed in the future.
However, for Deaf people, what is the utility in bringing a service animal with you, say, at the restaurant? Convenience store? Attending a function? I can easily see why many Deaf people would opt for a service animal in their homes to alert them to sounds, intruders. (I have a dog myself, just for this purpose.) But taking the service animal with you everywhere you go, this is where I'm not 'getting' it.
