David Wayne, a.k.a. The Jollyblogger, highlights a post from Tod Bolsinger today on the mandate Jesus gives to His followers for generosity, specifically in relation to the Christian's reputation with restaurant waitstaff.
It's a subject we've discussed a few times before.

Bolsinger, inspired by Tom Wright, writes:

In the middle of my sabbatical, while reading through a wonderful, thick tome on the ministry of Jesus by N.T. Wright, I stumbled across two words that were used to describe a key characteristic that Jesus’ expected of his followers: “astonishing generosity.” I liked the phrase. I rolled it around in my brain. But I also found myself disturbed by it. It seemed almost impossible.

The quote itself was a reference to Matthew 5:38-42, when Jesus tells his followers “to turn the other cheek” when struck, “give their cloak” when asked for a coat, or to carry a load an “extra mile” when a person makes you haul something for one. He is saying in effect, that even when people use or take advantage of you, they in the words of Bishop Wright, “must be met with astonishing generosity.” (Jesus and the Victory of God, p. 290)

Wayne writes:

One of the things [Richard Pratt] challenged me to do was to become a regular at the Bistro across the street. He said I need to go there often and our church members need to go there often. And, we need to be such excellent guests and tippers that waiters and waitresses want to fight over who gets to serve us.

This is a hot button issue for me. On more than one occasion I have heard and read people who say that wait-staff in restaurants do not have particularly good impressions of Christians and that for some, Sunday is the worst day of the week because of the church people. The church people are generally seen to be rude, demanding and poor tippers. So, Pratt's exhoration to me was to do my part in changing the reputation of Christians in that regard.

Sunday evening, Becky and I were dining out, and our waiter messed up our order in a few ways. He was very nervous for having done so. He ended up giving us a free appetizer and a free dessert. And even so, I could tell he was fearful of the compensatory repurcussions of his mistakes. I decided to give him a 50% tip, because even if he didn't know we were Christians, I wanted him to be astonished by grace after we'd left.

I don't say that to brag but merely to encourage you to think of small, practical ways you can extend grace to people. Not necessarily to "evangelize" or further your or the Church's reputation, but just because it is a Jesus sort of thing to do.
