There probably wasn't enough clearance on the end of the peninsula to have the conduit for the receptacle run up the side where the original plan was. For that, blame the cabinet designer.

If the code requires the receptacle, leave it as is for now. After the inspection make the cabinet guy replace that panel. You can remove the receptacle and cap off the wires (no loose live wires.. that's a no-no). And since the execution of the original design did not allow room for the receptacle, as designed, it's on the cabinet guy to make it right. You should not have to pay for that.

I can see where it would be useful to have a receptacle on the end of the peninsula, but on the back side like that is useless. Will cause a tripping hazard for anyone sitting there, or if you have a hot plate on the kitchen table, reaching over to the peninsula that's even worse.

Good luck.
