user
Perfect ! Can you please book a table for 3 people at Galleria for me on Monday at 16:30 ?
canthelp((_:booking,type,'Booking')) offer((_:booking,type,'Booking')) request((_:booking,day,?);(_:booking,duration,?);(_:booking,type,'Booking'))

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 ?
inform((_:search,duration,'15:30');(_:search,type,'Restaurant')) request((_:result,ref,?);(_:result,type,'Restaurant'))
user
Let 's try for 15:30 and can I get a reference number please ?
inform((_:booking,ref,'QBVP0ZV2');(_:booking,type,'Booking'))

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 do n't care about parking .
request((_:search,area,?);(_:search,stars,?);(_:search,type,'Hotel')) inform((_:result,amount,'fourteen');(_:result,category,'guesthouse');(_:result,type,'Hotel'))
system
There are fourteen different options for your guesthouse . Is there a specific area you would like to be in ? How about the star rating ?
inform((_:search,day,'monday');(_:search,people,'3');(_:search,stay,'5');(_:search,type,'Hotel'))
user
I do n't have any preference . Could you just pick something and book 5 nights for 3 people beginning on Monday ?
inform((_:result,name,'acorn guest house');(_:result,type,'Hotel')) canthelp((_:booking,type,'Booking')) reqmore()
system
Let 's go with acorn guest house . Unfortunately , that booking was unsuccessful . Want me to try something else ?
inform((_:search,stay,'3');(_:search,type,'Hotel'))
user
Instead of 3 nights how about two nights ?
canthelp((_:booking,type,'Booking')) request((_:booking,day,?);(_:booking,people,?);(_:booking,stay,?);(_:booking,type,'Booking'))
system
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 ?
inform((_:search,day,'monday');(_:search,people,'three');(_:search,stay,'two');(_:search,type,'Hotel'))
user
Certainly . Two nights , three people , and I 'll need that room starting Monday .
