M: Good morning, Patricia. How are you these days?
W: Fine, thanks, Bill. Glad to see you again. What news can you bring from your business trip to our headquarters in New York last week?
M: Well, not bad ones. During my stay in New York last week, I met our company’s CEO Mr. Johnson. He wants us to put on a local conference sometime next month. I remember you made most of the arrangements for our last conference, and things went so smoothly. I thought I couldn’t do better than ask you for some tips.
W: I’ll be glad to help. Is it a sales conference again?
M: Yes, in a way. It’s mainly for agents from home and abroad, and we’re inviting a few of our influential customers. The objectives are mainly to introduce the products we’re putting on the markets next season, to describe our services to customers and so on.
W: And how many people are expected to attend this time? Last time, it was about 220.
M: We’re counting on 300 this time. No more than 350.
W: Then we cannot use the seaside conference hall again. It has a capacity of only 250.
M: That’s the trouble. I was thinking of the President Convention Center, which has a larger capacity. Besides, I haven’t worked out all those details yet. Then there are other things to arrange, like loudspeakers and visual aids. I’m going to make a checklist.
W. Yes, I did that, too. I’ll be glad to give you a hand.
M: That would be great, Patricia. I’d very much like the chance of using some of your experience. May I invite you to lunch today? And then we could have a bit of planning session about it all afterwards.
