About 10 years ago or so, maybe longer, Bill Gates attended a conference at a hotel near my house where it charged $30 for valet parking. The story was that Bill Gates pulled up, asked "how much?" and immediately pulled out to park elsewhere.
Now if you think Bill Gates is cheap, think about billions of dollars he spends on charities every year. He's not cheap, but clearly he does not waste money. He spends where it's needed. So to Bill Gates, $30 is a lot to park a car, and it is to me as well.
