"how would Mrs Lee have coped in the pub or their kitchen? That's a situation more common in most of the collecting."

An interesting question. To Derek's reply I can add that Sharp and Karpeles in the Appalachians collected a lot of his songs in family homes, often eating with the family and very occasionally staying overnight. These occasions were cordial, and Sharp seems to have felt no discomfort either materially (in the local hotels it was a very different matter!) or socially.
