Kiefer Sutherland stunned bar staff when he bought all of their customers a drink.

The ’24′ actor and crew members of the hit US drama series popped into The Spot in San Pedro, California, after finishing a shoot, as they wanted to relax with a few alcoholic beverages.

According to an employee, Kiefer was enjoying scotch and cokes and decided to buy everyone in the venue – about 30 people – leaving him with a $500 bar bill.

He then left staff an impressive $200 tip when he left at the end of the night.

Kiefer is not the only celebrity to leave a generous amount of money.

Earlier this year, Johnny Depp gave a staggering $4,000 gratuity at a Chicago restaurant.

The 46-year-old actor was celebrating a red carpet screening of his new movie ‘Public Enemies’ with a group of friends – including his co-star Marion Cotillard and the film’s director Michael Mann – at Gibsons Bar and Steakhouse when he left the mammoth tip.

Waiter Mohammed A. Sekhani confirmed: “Depp hosted a party of 15 people, including Mann and Cotillard, and the tip was split 12 ways. Depp is the finest of all the stars I have ever waited on. And he is a true icon, and his ability to respect others is phenomenal. He loves Chicago, and Chicago loves him. Depp is one cool and generous dude.”

Kiefer, we always knew he was cool.
