If thought I had a reasonable chance of getting an interview in the near future, I would be asking those questions too. Especially if there's a significant other involved, you need to have time to think things through. When I hit the competitive ME time bar back in the day my phone started ringing, everybody called at once.

But there are occasionally folks with no 121 experience who obviously assume they are entitled to and will get their choice of several airline jobs...you just have to roll your eyes.
