  Bettina: Good morning Mrs Loder! This Friday? it might be difficult. What shall we do?
  Mrs Loder: I need the usual facial with peach peeling. And manicure with varnish.
  Bettina: I'm really sorry Mrs Loder but it's 2,5 hours and I don't have such a long slot free this Friday. How about Monday?
  Mrs Loder: That'll be too late. I'm off to Brittany on Sunday. And Saturday? Any time really.
  Bettina: I'm afraid I can't take any appointments this Saturday. So sorry! But maybe Thursday will suit you?
  Mrs Loder: In fact it does! But I'd rather have an appointment later in the afternoon.
  Bettina: 4:45?
  Mrs Loder: Any later slots?
  Bettina: 18:00?
  Mrs Loder: Brilliant. Thank you.
  Bettina: Thank you Mrs Loder.
