I was overcharged, people assume Musk pays for everything: Sister

World's richest man Elon Musk's sister, Tosca Musk, claimed she was overcharged for a filming location. "The location was going to cost $5,000/day…But when they heard my name...they decided to charge us $25,000/day," the 48-year-old said. "Everyone assumes my eldest brother pays for everything, but he doesn't," Tosca added. She's the Founder of Passionflix, a streaming service for romantic movies.
