The place she worked was like "the House of Eliot" only just before ww2. The workers didn't meet the clients, that was the job of the vendeuses (and the owner was French) They used to peep over the stairs to see her arrive and leave ands peep out of the windows to see the then Prince of Wales waiting outside in the car. She says that the fiction that "nobody knew" was just that in London, it was common gossip, they were seen out together and shopping but the papers kept it quiet so possibly not known outside of London.
