Sometimes I think it is in this bit from Bernard Malamud's Magic Barrel. Salzman the marriage broker has come to call on Finkel, aspiring rabbi perhaps in need of a wife:
"So good evening, I am invited?"Well, I guess you had to have been there. Anyway, Finkel answers "no."
Leo nodded, disturbed to see him again, yet unwilling to ask the man to leave.
Beaming still, Salzman laid his portfolio on the table. "Rabbi, I got for you tonight good news."
"I've asked you not to call me rabbi. I'm still a student."
"Your worries are finished. I have for you a first-class bride."
"Leave me in peace concerning the subject." Leo pretended lack of interest.
"The world will dance at your wedding."
"Please, Mr. Salzman, no more."
"But first must come back my strength.," Salzman said weakly. He fumbled with the portfolio straps and took out of the leather case an oily paper bag, from which he extracted a hard seeded roll and a small smoked whitefish. With a quick motion of his hand he stripped the fish out of its skin and began ravenously to chew. "All day in a rush," he muttered.
Leo watched him eat.
"A sliced tomato you have maybe? Salzman hesitantly inquired.
