what do you do
I frequently will ask for a question or theme we'll be addressing from a phone client when the appointment is requested, as I think it's more efficient to do a spread before the actual session begins, and sort of "hit the ground running" with the most pressing question.
Clients usually are pleased that they get this extra attention and I like stepping into the reading in a powerful way.
I would be cautious of a Reader who won't elaborate on the spread used or the cards that come up...I LOVE to explain the layout and the cards to a client, and some Readers who cold-read are, obviously, unable to explain the layout or cards because there aren't any!
Alternatively, this might be a Reader who is primarily an intuitive Reader, and feels pressured or judged by questions like this from a client.
If this Reader has been accurate and useful for this person in the past, I would assume it might be the latter.
This is just my opinion and experience!
