at australian service stations its a rule
to not sit on a motorcycle while filling..
some servos will refuse to activate the pump
if you dont get off your motorcycle to fill up..
similar typical requirement for removing helmet..
altho that seems based on experiences of riders
not paying, together with thieves robbing
business' wearing helmets..
servo lanes can have oil drips etc on them..
riders have slipped while sitting on their bikes filling,
resulting in bike down, incl on rider, petrol gushing out,
incl onto hot engine, including flash explosion/fire..
static electric charge can or may be generated from
rubbing fabric of pants on seat, causing ignition of petrol
being poured into tank just in front of rider..
similarly any fool can be smoking a cigarette
nearby and flick their burning butt into your space
and petrol vapour,, typical/predictable smoker habit..
