When you take your car in to have the brake pads replaced, the mechanic will phone you after he's had the car for an hour or two. He will say something like, "I noticed your rotors are looking worn. I could probably grind the rotors, but there won't be much left on them. We've got everything apart and could replace them for about 60 bucks each."

Now, you're left thinking, "Does 'not much left' mean 'not enough left'?" and it's a safety thing he's got it apart anyways and you didn't replace the rotors in the van and it blew a caliper that cost $450 to fix and are the pads going to outlast the rotors and and and ....
Down your mind goes in a spiral of Fear, Uncertainty and Doubt. Of course, the mechanic counts on this. Most of the time, it's what he sells.
"So, do you want sprinkles with that?"
