Quoted from Eryeal:I can't wait to find out what happens when OP finds out they don't pay for lunch ...
But they actually pay you distance-based travel allowance from your registered address to the courthouse. You can use this to defray vehicle costs and parking, or public transport costs or the costs related to having a friend take you there & back etc.
They go crazy explaining parking for a reason. You can pay a few bucks or pay more than your travel allowance for parking if you're not careful.
Although they don't tell you about the reimbursement, it's a nice surprise later. I once sat on a six week jury trial.
