There is something important in the arithmetic. The contribution of any particular teacher, mentor, or helper — however significant — is always bounded. The student has to take the gift and go. The taking-and-going is the larger part of the story, always.
Poitier understood this, which is why his accounts of the waiter are so carefully proportioned. He does not suggest that the man gave him his career, or his intelligence, or his drive. He says the man gave him the ability to read. He traces the consequences of that gift across his life. He does not inflate the gift or deflate it. He describes it accurately.
Accurate description is, itself, a skill. It requires the capacity to hold competing truths simultaneously — the smallness of the act and the largeness of its consequences, the anonymity of the giver and the public scale of what was built on the gift, the specific and bounded nature of what was taught and the vast and unbounded range of what was learned afterward.
Poitier held all of this, accurately, for the rest of his life.
He read pretty good. And he held it accurately. And those two things, taken together, are as complete a description of what the waiter gave him as any that can be offered.
