U: i need a train going to leicester that leaves after 11:45

S: Sure, are you going to leicester, or to cambridge? What is your departure site please?

U: I will be departing leicester going to cambridge, sorry for the confusion. I need to leave after 11:45 also.

S: The earliest train leaving after 11:45 is at 12:09 on friday. Would you like me to book this for you?

U: That is fine. Can I have the train ID once it's booked?

S: Of course, what day will you be traveling, and how many people will be in your party?

U: I need 1 ticket for departure on Thursday.

S: Great. I have booked you one seat on the 12:09 train from Leicester and your reference number is  7UR3BFW6. Is there anything else I can do for you?

U: Yes I want to reserve a table for 7 people at 15:00 on Thursday at an expensive African restaurant. Can you help me with this?

S: There are no tables available at Bedouin at that time. Would you like to try a different time slot or perhaps a different day?

U: Sure. If there are no other African eateries to choose from, try the 14:00 at the Bedouin.

S: There is one restaurant called bedouin, but unfortunately it does not have any open reservations for matching your specifications. Could you provide another day or time?

U: I need a place that has good quality dining and in a nice location.
S: According to the reviews left by the previous guests the location is not the best since it is not a busy part of town.
