I need help organizing a party for Mark.
At what venue would you like to have your party organised?
I'd like to have it at Southside Venue.
On what day would you like your party organised?
Ideally, on Thursday at 9 pm
How many people would you like to invite?
I'm expecting around 55 people to show up. 
OK, the Southside Venue would be happy to accommodate you on Thursday @ 9 pm.
Can I book it for you now?
What do you think the weather will be like that day?
Would you like to order any particular type of food?
It turns out that Mark won't be here on Thursday, so I'd like to change the date to Friday. I don't have any specific food requests for now. 
OK, the Southside Venue would be happy to accommodate you on Friday @ 9 pm.
Can I book it for you now?
Is it available on Friday at 8 pm?

Sounds good. I heard that the Southside Venue was close to some interesting galleries. 
Great, your party has been successfully booked at the Southside Venue on Friday at 8 pm!
Great thanks!
Is there anything else that I can do for you?
No, that will be all. Thank you.
Thank you and goodbye.
