Interesting points of view in there.
The part that caught my eye was
Imagine if my employee came to me and said, “My kid got sick, and I need to buy her some medicine. Can you advance me $250 against my next check?” and I said, “Sure thing, as long as you will go out with me.” We call that sexual harassment. If I demanded she sleep with me in order to get the money, we would call that rape.
The theme in the article is that the manager forced some sort of action onto the hungry man and made him accept it before giving him food.
Thing is though, there would have been no argument at all (I think) if the manager said "ok, I'll give you a meal if you wash all the windows in the store," because the hungry man would have been giving the manager something in return for something he wanted. (barter, one of the earliest forms of commerce.)
So really, the hungry man was doing just that. Exchanging his time for goods and services. The man could have done one of two things. 1) listened intently and maybe learned something he didn't know before, or 2) listened respectfully, knowing that he would be nourished afterwards, even though he wasn't particularly interested in the verbal message.
