In the movie The Big Short, there is a scene where two people. Bruce Miller and Mark Baum are doing a "debate" of sorts. The host introduces them as
... give a generous welcome to mr. Bruce Miller and Mark Baum.
In her choice of words, does she imply some sort of antagonism toward Baum by not introducing him as mr. as well, or perhaps greater goodwill toward Miller?
My main question is does the sentence "Mr. X and Y" puts them on equal footing, or should it be more appropriate to say "Mr. X and Mr. Y" or perhaps to use the plural form "Misters X and Y"?
