U: I would like to leave on Friday, after 10:30, please.

U: Could you actually tell me the price on that?

S: Of course, the cost for one ticket will be 16.60 pounds.

U: Great, thanks. Can you also help me find an upscale place to stay that offers free wifi?

S: Certainly, I have results for 5 upscale hotels with wifi and free parking. Do you have an area preference you'd like to stay in?

U: I don't have an area preference but I would like a guesthouse.

S: I'm sorry but I don't have nay guesthouses matching that criteria. Could we look at hotels instead?

U: Yes that will be fine.  Could you recommend a nice hotel?

S: I found 5 hotels, 2 in centre, one east, one west, and one south, would one of those work for you?

U: Are there any moderately priced guesthouses with wifi and free parking?

S: How about Home from Home, in the north of the city? 4 stars, moderately priced, free internet AND parking.

U: Do they have comfortable beds?
S: Home from Home gets mixed reviews on their beds.  Some patrons found the beds comfortable and others found them uncomfortable.  Can I help you with anything else?
