Uber chief says he must 'grow up' after argument with driver

San Francisco

UBER Technologies Inc chief executive Travis Kalanick on Tuesday said it was time for him to "grow up" and get help after a video was published showing him getting into an argument with a driver for the ride service who complained about pay rates.

Bloomberg on Tuesday published a video of Mr Kalanick, a co-founder of the company, arguing with a driver who tells him that rates have been cut and he has lost money.
