Lug back scratches with strap changes: piss you off, or not?

I'm not too bothered about it. I just assume any watch with a bracelet will show wear over time anyway where the bracelet interfaces with the lugs, and any watch with a leather or textile strap will need a change eventually when the strap wears out.

I'd get more bothered if I scratch links or mutilate screw heads when resizing a bracelet, but it's a necessary evil to get the practice in and get better at it (and get over it).

Edit: It would bother me to see a new watch that's been mishandled or someone showing no care or attention to detail, but it can still happen to the well intentioned.
