No, it requires corporate fraud, sadly the norm nowadays. I've been  
in trouble for being the "one honest man" before now - no names, no  
pack drill.

Nick's scenario is the most realistic threat - "Admission £5.00". I  
realise that you and Jennifer would never stumble into a low dive  
like that; unless you were with me, or Goodwins, or Oliver, or many  
of the other reprobates that you know. :=)

don't know why, but it does. I expect to be cited correctly. ;-) [Fx,
