Anyone lay their own concrete?

I'm a big fan of adding fiber. I poured a 2 car pole barn myself with the help of a teenager and a borrowed bull float. I came across the idea of adding fiber and going without rebar on the interweb and feel that even without rebar the fiber may have helped the reinforcement of areas that I screwed up. I underestimated the footage and was charged a screw up fee for having another truck show up. We made burritos while we waited for the second truck. Oh well.
