How Much Do You Tip? [POLL]

We have a lot of restaurants in Lubbock which means many of you go out to eat at least once a week. That means most of you have thought about how much is the right amount for a tip? 15%, 18%, or 20%? A recent article now suggests that 25% might be the new standard. What do you think is a good standard amount for a tip? Or is there a standard? Let us know what you think in today's KFYO Poll of the Day.
