People go to the hardware store looking for HOLES, NOT DRILL-BITS.
Don't sell drill-bits. Sell holes.

I now feel bad for all the times I was annoyed by retail sales people asking me questions about what I was doing. I thought they were being nosy. Sounds like they were actually well trained and trying to help me solve my problem.
And you do it holeheartedly, giving the customer the hole nine-yards.
It's a holesome experience, the fruit of a holistic approach.
