I feel the same as others have commented already, if we all approached them to call out their deceptive magazine hook lines none of them would want to man the carts anymore.
Where I live there is cart set up in the mall pretty much as permanent fixture these days mornings and afternoons. Same guy, same little boy who looks about 8-10 yrs old. The guy gets the little boy to walk up to people at the cafe tables and benches etc to hand out tracts and the people are like "aww isn't he cute."
Shameless. These people have no shame.
