A story from back in the day when gas stations had attendants who would pump the gas, clean your windows and check your oil. 

A minister waited in line to have his car filled with gas just before a long holiday weekend.

The attendant worked quickly, but there were many cars ahead of him in front of the service station.

Finally, the attendant motioned him toward a vacant pump.

"Reverend," said the young man, "sorry about the delay. It seems as if everyone waits until the last minute to get ready for a long trip."

The minister chuckled, "I know what you mean. It's the same in my business."
