[speaker001:] Can I help you?
[speaker002:] I'd like two kilos of eggs.
[speaker001:] What kind?
[speaker002:] Do you have the eggs with the red yolk?
[speaker001:] Sorry, madam. We have stopped selling those kinds of eggs for a week.
[speaker002:] Why?
[speaker001:] You know, red yolk is proved unnatural. It's artificial, and may lead to cancer.
[speaker002:] Oh, My God! That's terrible.
[speaker001:] Yes, so they are no longer being sold.
[speaker002:] Then give me the ordinary ones.
