No weddings yet. Several bar-mitzvahs.
I know the caterer isn’t cheating anyone. The OP is making the case that the soda should be banned because no one likes it. My point was that unless he thinks the ba’al simcha is being taken advantage of, why is it his business to begin with what someone serves at a wedding.
That being said, if a person really wants to serve something other than Be’er Mayim, he’s free to make his simcha at a different hall. No one is forcing him to use *that* hall.
