The Old Man Timeline and Summary

The old man sits alone at the café, getting drunk, and feeling the silence.
He taps his glass to summon one of the waiters; the younger waiter goes over and the old man asks for another brandy.
We're not sure how much the old man understands of what the younger waiter says, since he is deaf.
The younger waiter pours another glass of brandy, and the old man asks him to top off his glass.
The old man thanks the waiter. The two waiters watch him from the café, noticing that he drinks without spilling a drop, even when he's drunk.
The old man looks away for a moment, then asks for another brandy. When the younger waiter refuses and says they're closing up, the old man gets up, carefully pays, and walks away.
