From my church's weekly:
It was the start of a holiday weekend, and the service station was crowded. Finally, an attendant hustled up to the local minister who had been waiting in line for some time. "I'm sorry about the delay, pastor," the attendant apologized, "but it seems like everybody waits until the last minute to get ready for a trip which they knew they were going on all along."
The pastor smiled and said, "I know what you mean. I have the same problem in my business."
