Your spring fraternity party sounds like fun. We're glad you've again chosen us as your caterer. Unfortunately, we have changed a few of our policies, and I wanted you to know about these changes in advance so that we won't have any misunderstandings on the day of the party.

We will arrange the delivery of tables and chairs as usual the evening before the party. However, if you want us to set up, there is now a $100 charge for that service. Of course, you might want to get some of the brothers and pledges to do it, which would save you money. We've also added a small charge for cleanup. This is only $3 per person (you can estimate because I know a lot of people come and go later in the evening). Other than that, all the arrangements will be the same. We'll provide the skirt for the band stage, tablecloths, bar setup, and of course, the barbecue. Will you have the tubs of ice with soft drinks again? We can do that for you as well, but there will be a fee.

Please let me know if you have any problems with these changes and we'll try to work them out. I know it's going to be a great party.
