I had a visit from a family that I felt in love with. The parents were great, the kids were great, and I wanted them. I gave them a rebate. They are, so far, the best clients ever! They are respectfull, always paying on time, telling me how they like me, etc..... They are never trying to take advantage of me just because I was nice anough to give them a rebate!

But are they all like that? Probably not! But I would give her a rebate and you can make things really clear that it is a rebate but the rest of the contract stays the same (sick days, etc...)
