People like this you can't take personally.
I often can tell clients the same thing, in the same exact way, but until they hear it from my MALE bosses they don't always believe me.
And I have been treated this way from FEMALE clients and their family members too, so go figure.
Many times it's just the need to speak to the last person the feel is in charge.
I also have been told that I frequently know more than my male bosses too by a variety of people
