Here’s a good test for yourself—how do you tip servers at a restaurant? Not just the good servers but even the bad ones. Have you considered that tipping generously, even if the service is bad, is a demonstration of grace that is not likely to be lost on the server? Stop judging. Let the gospel compel you to live by grace and demonstrate it to those around you.
