Yeah, so they're spineless for not using good airmanship and taking extra when its needed, because they feel under more pressure.
Why do you think 200kgs is "a bit close to the wire"? I've not taken more than minimum fuel for weeks (rounded up to the nearest hundred), not because I'm under pressure to, which I suppose I am, but because there's been no need to.
Are you one of those types who always takes extra for no reason?
