It's all in the responsibility, and training. Obviously, that particular guide dog wasn't trained to leave it the hell alone. I grew up around dogs almost my entire life, and never had a guide dog. I wouldn't get one now, but *only* because if I'm gonna be spending 8 hours a day behind a desk, with the exception of maybe an hour for lunch to take it outside, the dog might as well spend that time at home where it's got free access to food and water. With that said, though, if any of the dogs I grew up with so much as sniffed at the plate, there'd be a stop put to that so fast it's not funny. Because anyone with half a brain knows what comes next. Obviously the particular owner is too lazy to train that dog not to and prefers instead to adjust his/her routine to suit the dog. Not your problem. Like chocolab said basicly, the dog doesn't make the routine. If anything, it'll built its own routine around yours. The most you have to worry about is it waking you up early morning (happened to me) to take them out simply because they can't hold it. Oh well. So they do their thing, come back inside, and you go back to bed. They'll live.
