re: How often do you barter goods/services?

Was at the in-laws this past weekend and took picture of my father in laws boat house. He had just had led lights installed all around it and the walkway to it (these were not cheap lights!)I took a picture of it while there during sunset. Told father in law to tell the guy he could use it for his business if he gave him something in return. He used it and is giving him some more lighting and a remote that he can turn the lights on automatically on the boathouse when driving up on the boat.
