They took no more long walks together when Marcus went out to exercise the dogs.

Nor did Marcus ever again recur to his generosity in renouncing Trina.
One Tuesday, as McTeague took his place at the table in the coffee-joint, he found Marcus already there.
"Hello, Mark," said the dentist, "you here already ?" "Hello," returned the other, indifferently, helping himself to tomato catsup.

There was a silence.

After a long while Marcus suddenly looked up.
"Say, Mac," he exclaimed, "when you going to pay me that money you owe me ?" McTeague was astonished.
"Huh?
What?
I don't--do I owe you any money, Mark ?" "Well, you owe me four bits," returned Marcus, doggedly.

"I paid for you and Trina that day at the picnic, and you never gave it back." "Oh--oh!" answered McTeague, in distress.
