Hi! I need to organize a surprise party for my colleague Angela who was promoted. Preferably at the Southside venue. Thursday at 1 pm would be great. 
May I have your name, please?
My name is Ben. 
How many people would you like to invite?
60 should be a good size party
The venue is too small for your party, we can try another venue if you'd like.
Let's keep the venue. We can reduce the number of guests. 
I am sorry, but it looks like the Southside Venue is not available then.
Change the date? I really think Angela is a super person. We really do not get to hang out much outside of work. 
OK, the Southside Venue would be happy to accommodate you on Friday @ 1 pm.
Can I book it for you now?
Do you hang out much with your coworkers outside of work? I think everyone should. 
I am sorry, I don't quite understand what you mean. I am only able to help you organise a party.
Can I make a request that no Thai food is served? Angela does not like it.

sounds good
Great, your party has been successfully booked at the Southside Venue on Friday at 1 pm!
Thank you so much. You have been very helpful. 
Thank you and goodbye.
