I set up a booth in public places with a lot of foot traffic. A sign at the top read “ASK”. Below that, movable letters spelled out “A LIBERAL JEW” on a marquee. I sat in the booth and answered questions as best I could. “Would you take a turn in the booth? You can change the marquee to describe yourself anyway you like,” I would say. Participants would man the booth until they wanted to take over again, or until someone else wanted a turn.
