Unstable Restaurant Table Solution

This came up Sunday so I thought I'd throw it out there for those of you who run into this.

Awesome Tip of the Day:  Next time you get stuck with a restaurant table that is threatening to spill your drink or food, fold up a paper napkin or two (better yet, dirty ones because it doesn't matter) into about one square inch.  Place the folded napkin(s) under the inadequate table leg for added security.  The table should more or less finally stand still.

Bonus, it's a good way to reuse that dirty napkin.
