Pet Peeve: vagueness presented as "opportunity" →[More:]
Them: Hi, we have a client in the area who wants a presentation on our brand of X.
[A presentation, or a contract? What, exactly? vagueness]
Me: I use more tools than just your X for such engagements. [response equally vague]
Them: Are you interested in talking with them or should we contact someone else? [frustration at my reflection of their vagueness]
Me: I prefer not to limit my tools, so yes, contact your other area consultants.[IOW, no money, no clear idea of what client even wants, no deal.Bye.]

Can we just speak English and say, We have potential client in your area looking for a local consultant who knows our business. Are you interested in meeting with them about what their goals are, and if it includes using our business product X, negotiating a fee so all of us can make some money?
