Do what i did when i was called for jury duty (yeh, yeh i f#ckin know ) anyway .. I told them i had been verballed by the Police on a number of occasions (true-ish .. ) therefore i could not believe a word a Police officer said .... Bingo , no more jury duty !!!... might work for you !!!!
Doesnt sound like Jury Duty, sounds like he cant get out of this one as he is being called as a witness. Bugger!!!!
Umm!! Sorry didnt se nuthin!!!! CAN I GO NOW (Might work - NOT)
I got out of all my call ups cos I have my own business that would be ruined with out me. cough cough
