Psmith in the City by P. G. Wodehouse

Life in a bank is at its pleasantest in the winter. When all the world outside is dark and damp and cold, the light and warmth of the place are comforting. There is a pleasant air of solidity about the interior of a bank. The green shaded lamps look cosy. And, the outside world offering so few attractions, the worker, perched on his stool, feels that he is not so badly off after all. It is when the days are long and the sun beats hot on the pavement, and everything shouts to him how splendid it is out in the country, that he begins to grow restless.

Mike, except for a fortnight at the beginning of his career in the New Asiatic Bank, had not had to stand the test of sunshine. At present, the weather being cold and dismal, he was almost entirely contented. Now that he had got into the swing of his work, the days passed very quickly; and with his life after office hours he had no fault to find at all.
