Is this normal for a car salesman to ask?

I am trying to finance a car. I am a woman and 31 years old. The car salesman I have been working with has been not very communicative. I have to check in with him through text and email to get him to respond to me (since I work a lot), however, when my father spoke to him, he gave him instant information and even deadlines when he’d call back and follow up. Unfortunately, he does not follow through with me often. I thought everything was good to go until he requested every single paystub from my current job and previous. I already sent him paystubs from my current job and even a W2. Is this normal to ask for?
