What do you think when the assistant is the wife?

Does it matter the type of business?

White collar scenario: fairly senior people in a corporation hiring a business consultant. If the person who takes the calls and does the scheduling for the consultant is married to the actual expert/consultant would it give you an impression that the consulting company is a small operation? A one man show? Would it be a turn off in any way?

Blue collar scenario: a business like a plumber or tile install. If the spouse takes calls would that affect your image of the company?

If either scenario does affect how you perceive the company do you think it’s reasonable for the wife (assuming she is the one in the administrative position) consider using her maiden name so there is no implication the owner and secretary are married?
