Stinking at Grace

I've written about this before, but Jon Acuff provided a light-hearted but important reminder that we, as Christians, shouldn't "stink at grace."

I run into these situations and realize I stink at grace:

1. When someone walks across an intersection I'm at and doesn't hustle.
2. When you poorly wrap my burrito.
3. When someone is slow to get off a plane.

You can read his explanations here. Can you think of any other examples where we can show more grace?
