Begrudging

I don't know if this happens to you, but I'm noticing it more and more. Someone offers you a refund, or agrees to sell you something or even hires you to do a project, but then spend a lot of time explaining that it's a one time thing, or that it's against policy or it's not even something they like to do.

What's the point of agreeing to anything begrudgingly? Does it get your partner to do his best work? Does it increase the chances that you'll get to win next time?

If you're going to do something, do it. Go all in. Doing it half in makes no sense at all to me. It's a like a store that has so many rules and regulations about sales and exchanges that you wonder if they really want to be bothered to sell you anything at all.
