I missed Jury Duty in Harris County; am out of reschedules, but...(details)?

I've gotten myself in a bit of a bind. Not long ago I missed a jury duty date (along with my two subsequent reschedules) due to my overnight work schedule not allowing me to arrive on time. I let my bosses know in advance each time but the people they lined up to relieve me in the morning never showed up on time.

Anyway, worried, I went to the internet naturally to figure out what the repercussions might be. The consensus seemed to be that in Harris County, the rate of no-shows is so high that hardly anybody is ever penalized.

However, just this evening, I received another summons in the mail...for tomorrow morning. Due to a change of address the letter must have gone through a long forwarding process and reached me late. And this time I am not allowed any reschedules.

The problem is...I'm at work right now as we speak. I'm here alone until morning.

I know several people have said that they never got into any trouble after missing Harris County jury duty, but I've never heard anybody mentioning getting ANOTHER summons for failure to show up. What will happen if I do not make it in time this time?
