I don't think this is the case here. I've been living away from home for 6 years now (though financial independence is something rather new still). My mother treats me like the adult I am and she expects no less of me than to make important decisions for myself. It is not the issue of making a decision, but making her feel more comfortable with my decision. She's not preventing me from doing anything, she just doesn't like it.
I think that in my particular case having her talk to a recruiter could be useful because a recruiter could give her some insight into Navy life and answer questions I may not be able to.
Persoanlly, I feel you should still separtate these into two events. Why not have your interview followed by an "Oh thank you LT/Chief etc for your time, but I have a request. Do you mind having a talk with my parents/parent offline about service life? She/he has some typical concerns that I'm sure you with your wealth of knowledge would better articulate. Thank you!"
That's just a tactful way of doing it. I see where RUFiO181 is going, but I would be WAAY put off if I were Officer recruiting and someone brought their mom or dad with them. Officer recruiting is not the same as Enlisted recruiting where I'm sure parents getting invloved is common. They (ORs) are looking for what you can do for them.
