Planning a big party can be pretty difficult. You have to figure out a budget before you’re sure how many people will come. You have to see to it that you’ll have enough food for all your guests while making sure you don’t buy too much.
Planning can become even more difficult when you’re planning for a really big event, such as a wedding. Catering companies often want you to pay well in advance, before you know how many people are coming. You have to guess how many guests are likely to come and leave room for last-minute arrivals.
