Ask HN: When to say NO to introductory meeting?
From time to time I have a new client which wants to meet with me personally and what is significant he/she refuses tell me what will be exact topic of the meeting. It cost me my time and transport expenses. I think they just want to bounce ideas around or pick my brain or whatever for stealing my time.
Do you think it is toxic client and it is OK to say NO?
What would you write/tell such client?
Do you know some interesting online strategy materials on this topic?
