Read it through once

He walked listlessly round Stephen’s Green and then down Grafton Street. Though his eyes took note of many elements of the crowd through which he passed they did so morosely. He found trivial all that was meant to charm him and did not answer the glances which invited him to be bold. He knew that he would have to speak a great deal, to invent and to amuse, and his brain and throat were too dry for such a task. The problem of how he could pass the hours till he met Corley again troubled him a little. He could think of no way of passing them but to keep on walking. He turned to the left when he came to the corner of Rutland Square and felt more at ease in the dark quiet street, the sombre look of which suited his mood. He paused at last before the window of a poor-looking shop over which the words _Refreshment Bar_ were printed in white letters. On the glass of the window were two flying inscriptions: _Ginger Beer_ and _Ginger Ale_. A cut ham was exposed on a great blue dish while near it on a plate lay a segment of very light plum-pudding. He eyed this food earnestly for some time and then, after glancing warily up and down the street, went into the shop quickly.
