Use the verbs in the correct tense : ... When he was gone, a tall pale youth with long hair, who (to wait) patiently

When he was gone, a tall pale youth with long hair, who had been waiting patiently for Mr. Bigger all the time, appeared in the doorway. His eyes were dark and melancholy; his expression, his general appearance were romantic and a little pitiable. “Sorry having kept you waiting,” said Mr. Bigger. “What do you want to see me for?” The young man hesitated. “The fact is,” he said at last, “I am horribly short of money. Can you pay me for that thing I did for you the other day?” “How much did we settle it for?” “Twenty pounds, I think.” “Make it twenty five,” said Mr. Bigger generously. “Thank you. I suppose you wouldn’t like to have a show of my landscapes.” “No, nothing of your own,” replied Mr. Bigger.
