I recalled that this alternative to coffee had been known as “ersatz”, and immediately I thought of the sugary grain bar which now took the place of good German bread. This unfortunate newspaper seller was embarrassed in front of his guest because the stranglehold of the British vermin allowed him to offer nothing better. It was an outright scandal. I was overcome with emotion. “It’s not your fault, my good man,” I assured him. “In any case, I’m not much of a coffee lover. But I would be very grateful for a glass of water.”
