Here in CLT we would get a jury summons but you didn't know if you had to show or not until 5pm the day prior. Of course that was useless for most pilots so the airline had to get me off the trip and home the day prior just in case I had to show at 8am the next morning. I served twice from 1990's to 2000's but haven't had a summons in 10-20 years now.
