ASSISTANT: Do you have any connection limit in between your journey?

USER: I need a connecting flight.

ASSISTANT: How can much you can afford for your ticket?

USER: I have mentioned above.

ASSISTANT: That for confirmation I have asked you again, please allow me a moment.

USER: Sure.

ASSISTANT: Here is I didn't find any flight with 200. I got a flight with 600, is it ok with it?

USER: As my budget is low, I can afford only 200. Is there any discount available for master card users?

ASSISTANT: Oh, that sad to hear. At this moment we don't have any discounts because it is a festival season. Now we can't give any discount on your ticket. Sorry for inconvenience caused.

USER: It's ok, thank you for checking.

ASSISTANT: Ok, thank you for reaching us.
