U: I would like to find a guesthouse to stay at with a 4 star rating.

S: OK, do you have a certain area or price range in mind?

U: I'd like it to be expensive, but have free wifi.

S: I'm sorry, there are absolutely no guesthouses that meet those requirements.  Can I look for something different?

U: How about a cheap one?

S: I have several guesthouses in the cheap price range.  Do you have a preference in the part of town?

U: I do not care what area.

S: How about the alexander bed and breakfast?  It is a guesthouse in the centre with 4 stars.  It includes free internet and parking.  Shall I book it?

U: Actually I would just like their postcode at the moment.

S: Sure, the guesthouse postcode is cb12de. Do you need help with anything else?

U: No thank you that will be all

S: welcome and have a nice day

U: I'm sorry I am also looking for a restaurant called bedouin.

S: Yes, it's an african restaurant in the centre. Would you like a booking?

U: I will try them if they have beer of the highest quality.
S: Okay, perhaps we should try somewhere else. One customer said that the beer was just okay.
