Sent over a bottle of champagne

Bono and a friend of his come to a restaurant and some guy is sitting in their usual table. Bono asks if the guy can move, and he does. Bono and the friend send over a bottle of champagne as thanks. As they are leaving, the guy asks Bono if he can get a photo with him. Bono agrees, and the guy gets Bono's friend to take the photo. Turns out Bonos friend was Bruce Springsteen, but the guy didn't recognise him.
