Twist the knife, why don't you 😀. I videoed the pour, and saw the concrete was going off before it was laid and there were voids forming. We had the slab tested for voids and several were found, so they took core samples and condemed it. All because they wanted to save money by not having to use a pump. So much easier the second time. Fortunately it didn't cost us a penny, but we did lose a couple of weeks.
