Is it a good idea to help prospects with tasks like plumbing? Usually I play dumb, but an unusual situation came up. I have a number of employees, one of whom happens to have plumbing in his skill set. While talking to a friend of mine this came up and he said, "Oh, you should tell X that, because she needs some plumbing to be done." X is the prospect whom we both know and my friend is a close friend of hers. Even if I don't mention it to her, there is a 50-50 chance he will now tell her that I have a plumber in my employ, so she might come to me asking the use of him.

How should I handle this?
