Dr. Martin Ellingham and Bert Large in “Unfinished Business”

Dr. Martin Ellingham

I want you to close this restaurant.

Bert Large

(Wanting to get out of earshot of his customers) Come into the kitchen. I put everything I've got into this place.

Dr. Martin Ellingham

Well, you're certainly putting something into it that's making people very ill, indeed.

Bert Large

I've eaten here, and I'm perfectly fine!

Dr. Martin Ellingham

Bert, you've spent your entire working life with your arm down a lavatory. You're bound to have built up a resistance to certain bacteria. The point I'm trying to make is that you are by profession and design a plumber, not a restaurateur.
