Interviews?

Hello all - I’m an independent bookkeeper with a roster of 8-10 clients currently. Recently, I received a client referral for a prospective client.

This organization reached out to me and I met first with Treasurer, then with Treasurer, several board members, and an administrator. All in all I’ve spent over three hours with them because they have good questions, a good organization, and came from a client.

A board member asked to know what my other clients think. Recently I’d sent a survey to my clients to ensure they are happy with my services. I shared some of the comments as well as results but the board member is asking to interview my clients.

Am I reasonable to feel this request is absurd and out of the realm of typical?
