Soaked and homeward bound. Apparently a nightmare

There is something especially hilarious about weather over-preparedness in New York City. I saw a gentleman walking his dog wearing knee high slickers and a poncho. He had the dog's leash in one hand and a humongous umbrella in the other.  It was barely drizzling. About 10% of the people on the street were rain gear equipped. Seriously - how far could he possibly be walking his dog? What exactly is the worst case scenario? That he gets soaked and then arrives home soaked? But, who am I to judge? Maybe he was planning an all-day walk with his  miniature dachshund. That would be a legitimate excuse. But, somehow, given the fragility of the dog and the heftiness of the man, I highly doubt that scenario.
