I filled out the questionnaire online for Dr. Pepper, got a confirmation number and e-mail. A few months later she got a letter saying that since she ignored the questionnaire she must either report to court the very next day or risk facing one year in jail plus a $1,000 fine. I called them, told them about the e-mail and they asked me to forward it to them. Never heard from them again.
As far as jury service is concerned, I never got called but Dr. Pepper did a few times. She just called and said that she’d love to serve on the jury but she’ll need a private room to feed the baby. They always gave her off for a few years. They might have made the system stricter recently though.
