Bruce Willis -- Big Christmas Tree, Big Christmas Tipper

No one is going to confuse Bruce Willis with Ebenezer Scrooge -- because the guy showed some serious Christmas spirit when he dropped a gigantic tip when he bought his Xmas tree this week.

We're told Willis dropped $175 on a 10-foot tree from A1 Christmas Trees and Lights in Los Angeles. The owner tells TMZ Bruce was really nice to everyone there -- shaking everyone's hand who asked -- but wouldn't pose for pics.

Bruce made up for it though ... forking over $100 to each of the guys who helped him pick out the tree.
