Likely not. But, that would suck.
Here is what the San Francisco Government website has to say about it:
Failure to Respond to a Jury Summons
If you fail to appear, you will be subject to a fine or imprisonment pursuant to section 209 of the california code of civil procedure. Section 209 requires the Jury Commissioner to pursue non-respondents. If you receive a Notice of Failure to Appear, you must contact the Jury Office at 415-551-3608 within 10 business days to reschedule your service or to explain why you cannot serve as a juror.
Let's just hope I spot the Notice of Failure to Appear if I get one.
