That one customer who taught me to pause before cutting
Had a guy come into my shop in Columbus about 3 months back, wanted a custom bookshelf for his daughter. He was real specific about the measurements, even showed me a sketch. I was about to cut the first board when he stopped me and said, 'I know you know your stuff, but can we talk this through one more time?' We sat there for 20 minutes going over it, and sure enough, he had one of the shelf heights wrong by 2 inches. Saved me a whole sheet of plywood. Ever since then, I always take the extra 5 minutes to go over plans with a client before I start cutting. Has anyone else had a customer catch a mistake that saved you time or materials?
