I’m unable to read all of the replies to this thread. But I am curious. Did the original email ask you how much you pay the techs? Or did it ask you how much you pay a specific tech? Or does a particular tech only go to this clients home?

If it’s possible that the client asked for a specific tech or only one tech goes there. Then is it possible that tech and the client was talking about a wage increase? That maybe a topic that your tech isn’t comfortable talking with you, yet, but is with someone else. Who happened to be the client, basically asking for advice.
