The actor splashed the cash as he ordered $1,000 worth of sushi and other Japanese dishes and gave the very generous tip to the stunned server at a family dinner to celebrate fiancée Angelina Jolie`s 38th birthday at Japanese eatery Kuchi in Berlin, Germany, on Tuesday (04.06.13).
Waitress Undine Orth, 24, told Germany`s Bild newspaper: "They are so cool. At nine o`clock at night, they were there at the door. They took their shoes off, like all guests."
The 49-year-old heartthrob reportedly ordered up a sample of everything on the menu for himself, Angelina and their six kids - Maddox, 11, Pax, nine, Zahara, eight, Shiloh, six, and four-year-old twins Knox and Vivienne - including sushi, salad, yakitori chicken and soup, which came to morethan $1,000.
After finishing the appetising meal, Brad whipped out $1,846 in cash and said, `That`s good`, according to awestruck Undine.
She said: "My knees were shaking. I shared the tip with 15 of my colleagues."
Brad, 49, and Angelina were in town for the German premiere of his new zombie thriller `World War Z` and spared time from promotional duties to celebrate the `Salt` beauty`s special day.
The hunky actor previously admitted he marked the special occasion by buying his fiancée - who recently revealed she`d had a double mastectomy operation - a "dirty" gift.
Quizzed what he bought for Angelina`s birthday, he said: "Oh, that`s private, very private. But it`s always something for her as a woman, as a mother, and something dirty. Always."
