A friend has a common name, the same as a famous restauranteur in town (Let's say John Smith).
He called a very hot restaurant and was told they had nothing, all night. When my friend asked if he could at least be put on a waitlist, they said sure, but don't bet on it. So he gave them his name anyway. Everything changed.
"Well, Mr. Smith, for YOU we'll have a table ready at 6:30, as you requested!"
My friend, quietly, thanked them.
