Would you get mad if your wives used there maiden name instead of there married name?

I am curious to know how many men would be offended if there wives were to you use there maiden name in business rather than there married one, the reason I asked this question my husband and I was watching Die Hard the other night and when John McClaine went to see his wife on her new job he noticed that she wasn't using her married name but her maiden instead, my husband felt that if she wanted to use her maiden name then she shouldn't have gotten married, well I disagreed with him and I say that it is nothing wrong with it if they are using it for business purposes and not for everyday so here is your chance to give me your thought, Do you agree with my husband that this is not okay for women to do? Or do you agree with me and see that it is okay to do only in business purposes only? I am ready for good answers! Good luck!
