Man, that is brutal. I had something similar happen a few years back, but it was the concrete plant mixing the wrong PSI for a driveway job. We didn't catch it until the truck was already on site, and the whole pour had to be scrapped. The thing that saved me after that was making my dispatcher call the supplier the day before to confirm everything in writing, not just over the phone. We also started putting a 2 hour buffer in the schedule for any delivery, so when someone is late it doesn't kill the whole day. It costs a little bit in planning, but it beats paying crews to stand around doing nothing.

My record is four rounds on a logo, then they picked the very first sketch I did in ten minutes. I guess that's the job sometimes, we all end up being paid for the ride not the finish line. At least you got paid for the extra hours, all I got was a headache and a lesson about showing my early drafts less.
