control joint chips

Hello,

i just got my pathway to my front step done by a contractor and when he made the control joint cuts there are little chips along the cut. he cut it within 24hrs fyi so didn't wait long.

my Neighbour just got theirs done and its a lot cleaner cut. my wife paid him already and hes coming tomorrow to seal, not sur e if hes sealing the concrete or the joints. not to knowledgeable about concrete.

should i say something? i paid cash, he seems like a nice guy, but what are the solutions really. its not super bad it just looks sloppy like the blade was dull or wobbly.
