On Friday I was in town and saw two young girls ( 25-30) on a cart. I said very politely " Do you realize you are in a cult". One politely asked why I said that, I very politely mentioned the royal commission, blah blah blah. She said " If I am wrong I will research it " I returned a little later, because having thought on our communication, I didn't want her to research and be without a contact. " can I give you my wife's number, so if you research and need talk with someone you have a contact" She thanked me put my wife's number on her phone....
That's the beauty of the cart, it catches many witnesses out of the witness mode, open to discussion and not on mind control alert as when they witness door to door.
