Hecce: It is possible that the two persons at the end of the sign are the publishers, they have been instructed to stand away from the carts; not to scare away the interested people with their presence
TheWonderofYou: Why should a nice smiling person scare somebody? Thats absolut stupid thinking.
Maybe not so stupid at all. As Hecce said, it's their 'presence,' not their 'faces,' that would scare people off. People could be scared away by someone's presence in the sense that they don't want to be engaged in conversation about religion or they don't want to have to hear a pitch by someone looking to make converts, not because the 'smiling faces' are frightening in themselves.
