I know someone who doesn't tip at all. Never mind the service, they refuse to tip because 'they already get paid for their job'. I also know someone else who only tips waitresses, but never waiters. He says it's because he feels bad for waitresses and what they have to go through, but guys can deal with it or find another job. I want to know, do you have any odd tipping habits?

Have you noticed you tip more based solely on if they're male or female? Maybe you tip more under other circumstances? Let us know.
