Yes , I book ahead so never used green light, means nothing to me, but never say never ! I have bookings lined up and I know who I want to see , so never use the light. Always have a plan, so always know weeks ahead what money I'm spending, fear if I did impulse punts , it could easily get out of control, because the very next day after a punt I'd be looking again, the way I do it , I can go over a week or more without looking at a w now.
