Thus the lower classes lived largely on dry bread, since they had insufficient fuel for cooking, but only enough to boil the occasional kettle. If they could boil tea to drink instead of beer, then they would have a safe source of drinking water, and hot tea twice a day might also be the only warm and comforting item in their diet.
因此，對於以乾麵包為主食的下層階級而言，如果能燒茶代酒，既能有安全飲水，一天兩次的熱茶也可能是他們唯有的熱食。
