An unappealing waiter

 There was no one in sight, so he tapped the counter irresolutely. Almost immediately a door to the right of the stove was jerked open and there appeared a mountain of a man with the largest and most lugubrious face he had ever seen. A small tablecloth had been tied across his stomch by the way of an apron, and his great muscular arms were bare to the elbow. For the rest, his head was bald, and the bone of his nose had sustained an irreparable injury.
