Winge from other side of the fence

I know allot of people have bad stories to share about workshops around the country from a customers point of view, so I thought i would tell a story from the mechanics side.
A customer booked in his Jackaroo for a set of brake pads very specific that the pads only be replaced no disc machining.
When I drove the car onto the 4 post hoist and put my foot on the brake the pedal when to the floor and the car stopped only by way of the stops at the end of the hoist, upon further inspection the reason for this brake condition was the fact that the customer had driven the car from Newcastle to Canberra metal to metal on the backing plates of the brake pad until it was so thin that it fell out of the calliper, then wore the piston of the to the point that it let all the brake fluid out of that calliper and hence no brakes at all.
When I rang the customer to inform him of what I had discovered, and the cost of the repair I was astonished with the reply " I wasn't expecting that much can you patch it up with new pads on one side?"
This is a person who was risking his own life and every ones life around him driving a car in this condition and still doesn't get it.
Rant over, just to let you know what we come up against from time to time
