I was on the committee for our high school reunion and was in charge of finding a restaurant for our Friday night casual event. I wanted to find a place near our high school and had a lot of choices. There are a number of nice restaurants in the old hood. I started going from restaurant to restaurant, talking with managers about reserving a space for us and collecting a lot of restaurant business cards.
Unfortunately, they all required a set amount we had to spend. I was OK with that, because if everyone just bought two drinks, we would hit that amount. But others on the committee kind of freaked out about it and didn't want that. They were afraid that if we didn't meet that amount (fat chance) that we on the committee would have to make up the difference.
So what we did instead was announced that we were going to a swanky restaurant in another part of town and didn't tell the restaurant! Yes, that is right. That night, the restaurant was a little upset, saying they didn't know we were coming and did not have enough staff. It turned out that about 100 people showed up for the event, but the restaurant handled it all very well. And they made a lot of extra money, and we didn't have to worry about a contract!
