I have to say I'm not very good at math, and I have no interest in trying to figure out what a 20 percent tip is on a $46.56 cent bill. I always make my spouse do the arithmetic. And you?

Whether we're dining at Texas Roadhouse, Cracker Barrel, or Julian's Asian Restaurant, we usually try to be generous with our tips. We know you guys and gals work hard for the money. And besides, we feel like we need to apologize for the discarded french fries and crayons and kids menus on the floor, tossed by our three kids. A good tip is a great way to say, "I'm sorry you had to put up with this nutty family."

Facebook founder Mark Zuckerberg is a billionaire and can afford big tips. Is he generous?

We've often heard stories of rich celebrities leaving without offering a good tip. Just because they can afford it, does that mean they have to be generous with tips?

On his honeymoon, Mark Zuckerberg reportedly dined out in Rome and failed to leave a tip after having lunch with his wife. In his defense, the tip may have been included in the bill, but some say he still should have left a buck or two on top of that. Wouldn't that amount have almost been an insult?

Oh the pickle these celebrities are in when it comes to tips! Everyone is watching.

All we can do is continue taking care of our East Texas servers. Thanks for keeping the Diet Cokes refilled!
