I believe the significant point is being missed here and it defaults to the most obvious that a business has the right to decide how it will spend their revenue, use their space, etc,etc. Of course they do. But there is an old
saying, "it is not what you say, it is the way that you say it". Since the people requesting the help felt abused then either they did not want to accept the rejection or the communications were poor. I would probably vote for the second as most people are receptive when they are treated with some dignity and with respect. The key word being respect.
