I had a similar situation in a tiny local shopping precinct a week or so ago. A man was seemingly collapsed against a wall just along a side street. As it was outside a shop, I got a local man who was in there to have a look at him. He was quite inebriated I'd say, and not terribly coherent. It was a bitterly cold day, and collapsed on the street was not the place for him. I didn't have my phone, so the other gentleman called an ambulance for him.
As an older lady, yes I'll stop...but I'll also get assistance from others.
