All the years I worked for a big corporation (who reimbursed for jury duty), I never got picked - I've been called 3 times since being self-employed - in each case a trial of more than a week would probably have put me out of business - but then they didn't actually end up assigning me. Oh well - not only do I feel it an important civic duty, but I think I'd find it very interesting... but why could they have asked me when it was less inconvenient??
