Buy coffee cards

We work above a small local coffee shop and cafe. I recently purchased a small stack of "free cup of coffee" gift cards that I can handout as a small real-time thank you for someone going the extra mile. It's not much, but it's something. The fact that it's real-time is the most important part I think. People appreciate quick feedback.

And, there's a nice side effect that the cards are burning a hole in my pocket. Because I have them, I want to give them away. That means I'm looking for positive things so I can reinforce them. That sure beats the alternative.
