I get a jury summons every year like clockwork. Sometimes my jury number is called, but usually I don't have to report. When I have had to report, most times I just sit in the jury waiting area all day and never see the inside of the court room. There, I can move about and use the toilet all I want.
The few occasions I had to go to a court room I wound up not being selected. I do tell the judge that I have inflammatory bowel disease with no colon and may have urgent need to use the rest room. They tell me to just raise my hand and they'll take a recess. The one time I got into the jury box for selection I wound up getting dismissed by one of the attorneys. Anyway, they typically would recess before I needed to raise my hand. My main complaint was that the court building is old, the bathrooms are in the basement, and the elevators are slow.
In my state you have to have a written excuse from the doctor to be waived from jury duty until age 70. Long story short, it has been OK for me.
