Church, Bistro and Theatre

Please, Please, no sarcastic or uninformative answers. I believe a acquaintance of mine has been scammed by a person posing as a church official. I know nothing of the Catholic faith or rites, and I don’t know if churches even sell holy water.

I know a pastor who is hosting a millionaire business seminar at his church and charging money for it. He has a for-profit business where he speaks on different subjects and charges money for the seminars but most of them are at the church. Isn’t that illegal?
The pastor is charging $89.00 per person for this event.
