I doubt the manager had to expose her breast to eat her lunch.
I'm sorry, I don't get the point of what you posted.
Public restrooms are filthy. I would NEVER nurse my baby in one - the thought of sitting on a dirty toilet, touching my baby with my hands that have handled the contaminated door latches and sink handles, makes me physically ill.
It is ludicrous to even suggest that women feed their babies in public restrooms.
I could feed my fussy babies in church, and no one was the wiser. Strategically placed blankets and well-designed clothing for mom make it impossible to see anything. I think people who object to breastfeeding in public have some sort of weird problem.
Neither did the nursing mother. She had a blanket for modesty.
