Unwanted help from normals tangles and disables the competent disabled

Evidence

A male, middle aged, is wandering about the bus depot. He is blind, or at least partially blind and has with him a mutt who apparently serves as his guide dog. The dog is wearing a special harness to aid in the signaling that must go on between them. A middle aged woman has been watching him for some time. He is now standing in front of the lunch counter, apparently preparatory to taking a seat. As he is standing there, the woman approaches, introduces herself and begins telling him about some people she knows who are blind and what was done for them and so forth. He listens politely for a few moments, then turns and begins to maneuver himself onto a lunch counter seat. The woman, noting this, desires to be helpful and she tries to assist him in getting up to the counter and on to a stool. In doing so, she bumps into the dog several times, changes positions and then gets herself, the dog and the man tangled up in the leash. During all this she keeps reaching down to pat the dog who is becoming more confused and excited all the time. Finally she leaves, the man orders coffee, finishes drinking it and leaves unaided; a far smoother departure than arrival. — Lyn H. Lofland, World of Strangers_ Order and Action in…, 489
