Sean mentioned an incident where he had sent in a book to Matt for rest removal to submit for SS, and when it eventually returned from submission it was in a two tone (restored) yellow/purple signature series holder. It happens. I guess each situation will play out differently on the customer complaint handing end of things.
I've heard situations where blue label books were sent in for a CPR or straight sub and were flagged for restoration, meaning CGC missed the resto the first time around.
I think what will be particularly interesting to see play out is the traditional overselling approach of their paper lab shooting too high with grades, clashing with CGC's historically conservative position on grading, and how customers will react when they were promised a certain grade. It's a slippery slope, because when there aren't any complaints (or kept low-key when they happen) it will appear as though the grade fix is in place to help their grading empire retain its sparkle and shine.
If instead the situation worsens (and by this I mean the heightening of work being missed or the temperatures of submitters start rising because the paper lab promised them a certain grade) then the question will become whether it was worth the additional costs/hassle and the negative trickle effect on CGC's reputation for the sake of getting in on the CPR action.
This is where I can see things having a chance of getting messy. If CI missed resto in the past it was down to them and them alone, but now with them being under the same roof as CGC then it will not pay for that sort of mistake to happen. Same in the event of CI predicting the wrong grade prior to pressing a book which then grades out lower than expected. It's no good having a 'pre-service' who promise you one thing when you end up with something different.
