If I can't use the window or pay at the pump, I ALWAYS take my lid off...
My 17 year old daughter worked in a petrol station.
All this talk about 'If I was gonna rob the place I wouldn't take it off'... well, exactly, that scares the youngsters as they're told you could be a possible robber...
Also it's been said that the cctv has your number plate... Yep all robbers use their own bike don't they...

Also, that no longer applies, the police don't pursue 'Drive offs' anymore.
I am often thanked by the cashiers for removing my helmet, and my reply... 'No probs, Why wouldn't I take it off, only takes 2 seconds'
