From my own experience of windscreen repairs, if the chip is anywhere near your line of sight when driving, I'd give it a bloody good tap with a centre punch and hammer before the guy arrives, just to make sure they can't attempt to repair it...
I've had 3 repairs previously and everytime I could still see it afterwards and it kept catching my eye when driving. And your insurance company won't replace a repaired screen because you don't like the repair!
