‘A lodger in a house, although he has the exclusive use of rooms in the house, in the sense that nobody else is to be there, and though his goods are stowed there, yet he is not in exclusive occupation in that sense, because the landlord is there for the purpose of being able, as landlords commonly do in the case of lodgings, to have his own servants to look after the house and the furniture, and has retained to himself the occupation, though he has agreed to give the exclusive enjoyment of the occupation to the lodger.’
