Celebs like Lindsay Lohan should take note — here’s a way to get good publicity. Following the premiere of his new movie, Public Enemies, Johnny Depp went to dinner at Gibsons steakhouse with several friends, including co-star Marion Cotillard and director Michael Mann. After the meal, he left the waiter a $4,000 tip. Speaking to RadarOnline, waiter Mohammed Sekhani said: “He may be one of the most famous actors in the world but he is a very humble guy and a really cool dude. Obviously, I was delighted with his tip but he has always been very generous every time that he has visited us here at Gibsons. He is a very soft spoken guy who is very charming and sweet — when I wait for him he doesn’t like to be too fussed over and is not in any way demanding.” Not only that, but in the past 16 months, Depp has also helped a girl in a coma; risked his life to save extras; and sent a fedora from Public Enemies to a young boy who admired it, in a package that included gifts for the boy’s siblings. Public Enemies opens on Wednesday, July 1.
