I don't know how it works everywhere else Benjamin, but out here they would admit a blind person with a dog without batting an eye. At least locally (and this may be a national interpretation), Seattle-area stores don't stop any entry from anyone with a dog or other animal, as long as they contend the animal is to meant to assist them. Those restaurants that advertise "No Animals?" I have seen one restaurant admit a Helper Ferret to dine with its owner. I would think that actually walking into a theater with a dog would be pretty mundane by comparison. Sure, some folks will push it, but for the most part people really use these lizards, cats, dogs and ferrets to help them out. <shrug>

Besides, not everyone with a guide dog is totally blind, and the sight-impaired folks I know tend to pick up on more than I ever could. I suspect they can follow alot of movies alot better than I could.
