Deadbolt job today. Two DB on a new home.
Back door turns out to be short backset. Went to change the bolts, get different bolts out of the van.
Came back in, install the DB. Then go to front door which had the long bakset. I hate it when that happens. fortunately, I was paying attention and didn't drill a Kwikset offset backset for the lockset. Make the customer upset. Couldn't then fix it with a pinset, or drown out the yelling with a headset.
