Such a program is "Short Order" from August 16, 1945. It features Joseph Kearns as the owner of a diner who must contend with a disfigured customer whose presence is depressing his business. This is all that's required for the bulk of the program - the tension between the owner and the customer as the former tries to save his business from ruin. Then, just as the twist ending seems to have been revealed... it explodes into a terrifying climax. You may download it from archive.org here.
Joseph Kearns' voice was frequently heard on Suspense in supporting roles, narrative roles or to shill products for the sponsors. In my opinion, he gave his finest performance in this outing. In all, he was a talented radio performer in both drama & comedy.
