An elderly man stands in front of his GP in his office in King's Lynn...

Aidan Sorry, I'm so sorry. You weren't waiting an entire hour, were you?

Ed About 55 minutes, it was.

Aidan Well, that's not an hour, is it? You can see we're a little behind.

Ed I was the first patient.

Aidan But we're behind from this morning, you see? Could you hold on a moment - it's really not easy for me on a day like this.

Ed It's not easy for me to wee, actually.

Aidan Right. That's fine. Right. Then let's have a look at the flexibility?

Ed The flexibility of what?

Aidan Of your knee.

Ed I didn't say knee.

Aidan OK. That's... wonderful. Fine. [Pause] I'm sorry, I was just checking something else. Sorry, Mr Hilton. Now, your knee?

Ed It's not my knee. I'm not Mr Hilton.

Aidan Of course you're not... Oh, I see. I'm writing on hotel stationery.

Ed That won't do for a prescription.

Aidan No. Please sit down. I'm so sorry.

Ed I can't sit down. That's the problem.

Aidan Of course. Sorry. Our computer's down. These NHS computers...

Ed I can tell you the problem.

Aidan Well, it should be on the computer. Someone got coffee on the keyboard. Now, some urine perhaps?

Ed I did that a few minutes ago.

Aidan Ah, right - and how did that go, urine-wise?

Ed I gave the full container to you. It's all very painful these days.

Aidan You gave the urine back to me, did you?

Ed I'm worried about this. About relapsing...

Aidan And the urine? Did you notice where I put it?

Ed Over that side of your desk.

Aidan Past the sandwich? So it's got to be either this vial or this one?

Ed I filled only one.

Aidan I'm sorry. We're very busy. Would you be able to... recognise the colour? Mr Hilton?
