I'm going to give her $5 (big spender, I know) but just between you and me I wouldn't have blinked if she'd asked for $10-$15-$20. I really need to get going to work, and wasn't looking forward to having to deal with the sidewalk beforehand.
UPDATE: Jenn points out that the girl's out there spreading salt on our sidewalk, as well. Now that's service.
UPDATE #2: Jenn points out that the girl has disappeared after talking to her mother. Perhaps she didn't get permission to use all their salt on the neighbor's sidewalks...
