I don';t want Him to know I';m here

A distinguished clergyman and the elders from his congregation attended an out-of-town meeting that did not finish until rather late. They decided to have something to eat before goint home, but unfortunately the only spot open was a seedy bar-and-grill with a questionable reputation.　
　　After being served, one of the elders asked the clergyman to say grace. ';I';d rather not,';, the clergyman said, '; I don';t want Him to know I';m here.';
