Washington, Aug 17 (ANI): Brad Pitt is sure to be welcomed with open arms wherever he goes, for he happens to be a great tipper.

The star spent a day with his family at Chicago's Field Museum and were treated to a one-hour VIP tour recently, and while leaving, handed a 300 dollar tip to the security guard who looked after the Jolie-Pitt clan on their visit.

"They were a nice couple," People quoted the guard, as saying.

Though the museum closes at 5 p.m. it stayed open for its special visitors.

And the family certainly had a lot of fun, for once there, Pitt and Jolie made wax dinosaur toys out of a molding machine with their kids - Maddox, Pax, Zahara and Shiloh, and checked out the extensive collection of dinosaur remains and fossils.

The next day, the couple finally got some time alone when they enjoyed a romantic date at Avenues, the Peninsula's contemporary American restaurant. (ANI)
