|Here's probably what the Specialists are up to...|
For a start, someone needs to tell some dickhead at Apple that 'same day' repairs and 'within 24 hours' ARE NOT THE SAME FUCKING THING. If you dropped your computer off at lunchtime on a Thursday to be told it will be ready and repaired on the same day, too fucking right you're gonna expect it to be ready on Thursday evening. If Apple can get it ready for you Friday morning, they consider that 'same day'!! It's fucking laughable! What fucking planet are they on. Friday is not Thursday, thus not SAME DAY. Stupid. Cunts.
In order to get these topcases switched over by the next morning, you may find that as a Genius, you need to be repairing until midnight. After a long day of swapping phones, I can say they last thing I wanted to do was start repairing computers. I'd probably spend 2 hours replacing a screen on a unibody white MacBook and give the manager some bullshit story about how "the DFI ribbon-micro cable is really difficult to fit on this model", whist thinking "I'm secretly lolling in your face right now"
Seriously though, who wants to spend their life repairing shit computers until midnight? You're not gonna get in until 1, asleep 'til 2, and if you're on a clopen, then you're fucked mate.
