someone mentioned needing an Old Korean Lady in the dramatisation.
I agree, she could be making kimchi on one of the other allotments, whilst desperately straining to overhear what was going on
Elderly Korean Lady was my suggestion. Luckily there should be plenty of cabbage around for her to get a head start on the kimchi, which as any fule kno must be fermented for a period of time. She can set up a field kitchen in Barbara's shed.
