THE DENTIST. It's my landlord's.
THE YOUNG LADY. Does he own that nice comfortable Bath chair? (pointing to the operating chair.)
THE DENTIST. No: I have that on the hire-purchase system.
THE YOUNG LADY (disparagingly). I thought so. (Looking about her again in search of further conclusions.) I suppose you haven't been here long?
THE DENTIST. Six weeks. Is there anything else you would like to know?
THE YOUNG LADY (the hint quite lost on her). Any family?
THE DENTIST. I am not married.
THE YOUNG LADY. Of course not: anybody can see that. I meant sisters and mother and that sort of thing.
THE DENTIST. Not on the premises.
THE YOUNG LADY. Hm! If you've been here six weeks, and mine was your first tooth, the practice can't be very large, can it?
