U: I need to get to Cambridge by 10:30, is it possible to do that by train?

S: Where are you leaving from? And what day do you need to leave?

U: I'll be leaving from Ely on Monday.

S: We have three trains arriving by 10:30. What time would you like to leave?

U: What time would I need to leave in order to arrive by 10:30?

S: I would say you should leave by 09:35

U: Ok can i get the train ID and price?

S: TR2987, fare is 4.40 pounds and your trip will be 17 minutes.

U: Great. Thank you. I'm also looking for a moderately priced, 4 star hotel.

S: There are many to choose from. Do you have a preferred area?

U: I don't have a preferred area, but I am looking for a hotel, not a  guesthouse. Does that narrow it down?

S: Unfortunately there aren't any hotels that match that criteria.  They are all guesthouses.

U: Ok, a guesthouse will have to do. How many choices do I have?

S: There are 11 choices.  Picking an area of town will help to narrow it down.

U: Please pick the best option. I need a room for 8, for two nights and starting Monday.

S: Booking was successful for the a and b guest house. Your reference number is : 1HPJ1F1W.  Do you require any further assistance?

U: Wait, can you check if they have dirty rooms or not, that's a deal break if they do.
S: It looks like the rooms are not as clean as you might expect. Let's go back to that list of options and find something better.
