Allyson Kazmucha on not being able to self-repair Apple devices:
Not only because it would hurt me but because it hurts my clients. Some of them just don’t have the money to walk into an Apple store and drop another $200 or more on a brand new replacement device. But they can afford to buy a part and swap it themselves or pay me a more reasonable amount to fix a shattered screen, broken home button, or replace a battery. They walk out happy and the odds of them purchasing another Apple device is more likely. They have the security that if an accident does happen, they have a safety net — either their own repair skills or businesses like my own.
This is why you don’t base your business around relying on someone else’s business.
