LoL. I think you'll get more "credit" than you think. A deposit in the emotional piggy bank at least from the folks whose photos you fix and maybe even the photographer whose face you are saving.

We all make mistakes (I recently stood up a client as we know, AND I made a referral to another photographer that ended up in a HORRIBLE session for another client), it's how those mistakes are dealt with that counts.

Hopefully, she'll remember that she "owes you one."
