I'd feel pretty cheeky helping a blind person if I was doing it just to get paid for it.
Similarly, I wouldn't help an old lady cross the street then ask for a pound.

Such a setting could even be on a per-case basis. Imagine if you helped someone for a good part of a day, and they were ready to return the favor in cash, and you were given the choice to accept or decline it.
