Every once in a while, something gets pushed at me that I cannot imagine having imagined. The usual portal is BBC Radio Four. On this occasion, that means its In Touch programme, and the issue is the eternal war between guide dogs and escalators.
Guide dogs, you see, are meant to be able to take you everywhere, and escalators are not meant to be walked with paws. In America and, by the looks of it, Australia, they train you to walk the dog up, in the belief that you'll do it anyway. In Britain they tell you to carry the dog, and concentrate on teaching you how to balance while holding something heavy and alive.
It's a Tube thing, apparently. New escalators will be dog-friendly, but given that old ones could hang around for decades -- see this wonderful piece for more on the subject -- that may not be much of a comfort.
