I usually just say I'm not interested, and hang up, but I got a call from a woman working for a very well-known PO polling company (read: commissioned call center) about fifteen minutes ago, and she sounded so hesitant, apologetic, and downright scared that I decided to respond. Maybe her approach was all a ploy? Anyway, I told her right away that I wasn't a German citizen and therefore couldn't vote, but that I was politically opinionated, so she'd have to decide whether it was worthwhile interviewing me. The poll turned out to be all about telecommunications (land lines, cell phones, fax machines, Internet access and use), so I actually found it interesting. How do you react to such calls? I fear that I'm usually impolite.
