Incidently, I was out in service A LOT - I auxied for a while, and my mother was a regular pioneer. So, naturually, I got to see who went out and who didn't. I'd say about 1/5 of the congregation really went out regularly, and, of those (who went out regularly), they did seem to enjoy it.
I suppose logic dictates that, to be a publisher in good standing, you had to turn in time - so the other 4/5 of the hall MUST've gone out at some point, but I never saw them (in fact, on the few times when everyone met at the hall on Saturday instead of their groups - it being a BIG social occasion and chance to get in the car with sisters from another bookstudy - I'd say about 75 of the 200 showed up).
IOW, I'd change your observation, at least for the 3 halls I had a lot of exposure with - I think, of those that actually went out, many enjoyed it. I'd suggest, however, that a lot more than is suspected lied about their time or 'informally witnessed'.
