I'm looking for a restaurant in the center of town that serves european food.
There are several that suit your needs. Any preferences on price range?
Moderate price range, please.
The 4 matching restaurants are "hotel du vin and bistro," "galleria," "de luca cucina and bar," and "riverside brasserie."
Perfect! Can you please book a table for 3 people at Galleria for me on Monday at 16:30?
Booking was unsuccessful. Would you like to book another day or time slot? Or perhaps another of the restaurant choices for the same booking information?
Let's try for 15:30 and can I get a reference number please?
Ok. That worked. It is booked and your reference number is QBVP0ZV2.
Great! I also need a guesthouse with free wifi. Something moderately priced, and I don't care about parking.
There are fourteen different options for your guesthouse. Is there a specific area you would like to be in? How about the star rating?
I don't have any preference. Could you just pick something and book 5 nights for 3 people beginning on Monday?
Let's go with acorn guest house. Unfortunately, that booking was unsuccessful. Want me to try something else?
Instead of 3 nights how about two nights?
There seems to be an error. Can you please restate your preferred number of nights, the day you'll arrive, and the number in your party?
Certainly. Two nights, three people, and I'll need that room starting Monday.
Great! Your booking was successful. The reference number is TWU9EM7U. Do you need help with anything else?
I don't. Thanks so much.
You're welcome!  You have a great day!
