Does anyone believe that a "talk with the shop owner" will accomplish a damn thing?

The only response you can possibly get is that "we're sorry" and "we'll try to do better next time".

If he says it with conviction, you might even believe it.

Can he ensure that his employees perform any better than they do for the next customer? I sincerely doubt it.

In my own business, I've had ongoing screwups in the designs for the better part of 10 years. There is always a statement that they are sorry and that they will try to do better in the future. Sadly, it never happens.

People are internally limited in most cases. The mistakes they make are ongoing and rarely improve with time. The only solution is a different employee, however, that brings the entire training issue into play and the investment of nearly five years is necessary just to determine if the individual can play the game in a decent fashion. Accuracy on every project is never assured.

The average person isn't going to achieve anything better than 90%..........the remainder are "mistakes"............"sorry".
