Even if I heard it on TV/radio I would still asked someone about the service, etc.... How many times have you saw something on TV/radio and then come to this very forum and asked others about it. I agree with Papasage. Word of mouth is the best form of advertising.
I vote NO I wouldn't do it unless there was time taken during at least one show to meet and greet owner.
Birddog,
I pray that I may live to fish until my dying day. And when it comes to my last cast I then most humbly pray. When in the Lord's great landing net and peacefully asleep. That in His mercy I be judged, BIG ENOUGH TO KEEP.
