Jeff Bezos tweeted a picture of himself eating a McDonald's burger on Sunday.
The Amazon founder's first job was at the fast-food chain at the age of 16.
He came under fire for seeking to dismantle a Dutch bridge to get his superyacht out of a shipyard.
He might be worth $154 billion, but it seems Jeff Bezos still enjoys some simple pleasures in life.
"I was a grill man and never worked the cash registers. The most challenging thing was keeping everything going at the right pace during a rush," he told Cody Teets for her book "Golden Opportunity: Remarkable Careers That Began at McDonald's."
"The manager at my McDonald's was excellent. He had a lot of teenagers working for him, and he kept us focused even while we had fun."
Bezos reportedly studied the fast-food chain's workflow technology and brainstormed improvements while working in the kitchen, Wired has reported.

The bridge, known as De Hef, is nearly 100 years old, and while it is no longer used has become a much-admired monument in the Dutch city.
