Foyle and Rook washing dishes in the shop sink in the bathroom because their kitchen doesn't have one, yes that checks out.

I have to wonder who's let the dishes pile up, though? Like just looking at that mess I have to assume it's Foyle's turn to wash dishes and she's ignoring them and Rook refuses to clean twice in a row so it's piled up. Because that is 100% how their relationship goes XD;
