I've seen something worse! Once had a 5C come in for repair. Still under warranty, so sent it to and Apple Store in the USA for replacement. We don't have an Apple Store in my country. Got back a unit that upon reception didn't start. Lifted the screen to inspect it out of curiosity, because it looked somewhat used from the outside, before proceeding to send back to Apple (and waiting another 3 week for the trip back and forth) and saw a device missing plates, screws, with a sticker inside with some Chinese words, and the red LCI (water indicators) were tripped (meaning the unit was water damaged prior). We sent it back and they declined to replace it again because... it had liquid damage and was tempered with!! After much aggravation, they accepted to replace it OOW (they usually don't replace devices that had been tempered with even OOW). Since then Apple Certified Service Providers in my country were allowed to replace iOS devices under warranty, and we did receive defective units on a few occasions that were fortunately replaced. But the second worse "incident" was my 15" 2011 laptop that had the logic board replaced 3 times under the Apple logic board program, before I got back a working unit! The ACSP told me that it happened many times over, but only (?) twice did they have to replace the same board 3 times in row! They're all refurbished boards of course (nothing wrong with that), but their QA after refurbishing seems to let a lot of bad Apples (pun intended) through!!
