U: I would like to go and visit Leicester. Do you think you can help me find a train to get me there?

S: Sure! There are plenty of trains going to Leicester. What city will you be departing from?

U: I will be leaving from cambridge.

S: Perfect. What day would you like to travel on? Do you need to depart or arrive by a certain time?

U: I will be traveling on Sunday and would like to arrive by 08:30 please.

S: The first train leaves at 06:21 and arrives at 08:06. How many tickets would you like please?

U: I need it for eight people, please.

S: Great! You're booked on TR9187 with reference number MJJ7J6CV. Is there anything else I can help with?

U: Yes! I also need to find an expensive guesthouse in the north. It should have plenty of free parking for my fancy car.

S: I am sorry, there are no expensive guest houses in the north with free parking.  Would you like to try another area?

U: Then how about one that is in the cheap price range?

S: There are 2 options. City Centre north has a rating of 0 stars and Worth House has a rating of 4 stars. Would you like me to book either of them?

U: Can you find out if Worth House has comfortable beds?
S: From the reviews, I see most people feel their beds were really comfy while some others said it was not so comfortable at all. Would you like me to find a place with better ratings?
