because one day's work and $100 isn't going to change anything. it's a pointless offer that was only extended because someone couldn't or didn't want to do the work themselves.
you don't see homeless people with horses, do you?
You missed on all the points. They were doing it to be nice to people. Our friends own horses and train horses for other people, so they are doing that stall cleaning themselves all the time.
And your "homeless people with horses" comment is worthless.
