Let's not rip into him too bad. Granted, the joints are wide, but overall it seems pretty decent. Perhaps his client preferred the joints wider. The patio looks well graded and the stone layout is good... except for the few small stones. Overall, it's not as horrible as some of you make it out to be. Just take the criticism with a grain of salt and use it to to better on the next project - that's what this site is all about.
