Oh I'm glad you asked , because I'm sure I've seen her as well and I think I half know the answer. There was a programme a year or two ago where 2 families were masters and servants (alternating a week as masters and a week as servants). They had to cleanthe other families house , shop and wait on them and then the following week the other family would do the same .The "servants would live in a caravan in the "masters " garden. I think it was a Channel 4 programme.
Ring any bells?
