"A little more," he said. The waiter poured on into the glass so that the brandy slopped over and ran down the stem into the top saucer of the pile. "Thank you," the old man said. The waiter took the bottle back inside the cafe. He sat down at the table with his colleague again.
Here, we see the old man's dependence on alcohol; he needs to be drunk every night to survive everyday life.

The old man looked from his glass across the square, then over at the waiters.
The young waiter, unsympathetic to the old man's troubles, is incredibly condescending to the drunk man, as though his drunkenness means that he's stupid. However, being drunk certainly doesn't signal being oblivious here – the implication is that the old man knows better than the young one.

"You talk like an old man yourself. He can buy a bottle and drink at home."
Why should it be any different to drink alone in a well-lit café, or to drink alone at home? Even the impatient waiter agrees that these are two different things – drinking at the café means something much more, though what exactly that is, we're uncertain.
