Uber, one of the new car services that you connect with through an app on your phone, imposes a surcharge during times of the day when drivers are in short supply. Like when it's snowing in New York — or apparently just early evening in Los Angeles. A woman says she found out just how that works on a recent Saturday night. To go 14 miles from West LA to Hollywood, she says her credit card was charged $357 — the service says it's not a mistake and that she knew the hefty surcharge was coming. She denies it. In any case, for that price she could go to Hollywood maybe ten times by regular old taxi. She probably could rent a limo for a couple of hours for less.
