This was a top of the line restaurant and the produce was usually perfect.
I suspected that was so when I saw the picture that you showed. It indicated that the lettuce you purchased was the best of the best.
That is good because that is what your business required.
But that best came out of a field of mostly imperfect heads of lettuce.
I am sure that if your supplier didn't provide the best that you would have rejected the lettuce and told the supplier that you did not want to see that label again.
And, if the supplier couldn't or wouldn't supply the quality that you required, you would find another supplier.
That is how the produce business works. If I were in your place, I would do the same.
