I read the article - I always find these kind of articles frustrating. They are trying so hard to be objective that they give the impression of endorsing the idea that women shouldn't breast-feed in public.
I don't necessarily think the article meant that, but it was definitely ambiguous.
That employee was horrendously out of line, though! I cannot believe she treated that mom in that manner. No wonder so many people don't breast-feed, if that is the kind of abuse moms are subject to.
