Love this Richie,
A good way to do this is giving it to them and ask if they would like to display in the coffee house a couple more of your work and offer it for sell. Sometimes it works very well.
Display the work and a nice bio and a great description for the piece, so customers can see that they buy from the artist direct and support art.
I'ts a win win, they have free art on there wall, and get it replaced, once sold. Much better for a java joint, than department store pic's. Makes the place cozy, gives it personality and class.
