I'm the opposite, half the time i forget the belt is there until i can't get the restraint to open.
remember hearing last year an experienced ride op (of about 5 years) was on a flat ride with over shoulder restaints. think he was having a blonde moment when he couldn't get the restaint to open so calls for a mechanic. the mech comes over, walks into the centre of the ride spots a restraint down with the belt done up, so unclips it."whats the problem then?" how much of an idiot must he have felt?
i wouldn't bother undoing the belt, there may be there as a last resort, but the chances of ever needing them are so remote with the safety factors used in the engineering that i wouldn't worry if they weren't fitted atall
