Welcome to the 175th episode of the Inc. Uncensored podcast, hosted by Inc. editor James Ledbetter.

This week, Inc. editor-at-large Burt Helm discusses his four-month-long investigation into HelloFresh, the German meal-kit company that clawed its way to the top--but not by playing nice. In the summer of 2015, the company's warehouse staff mutinied, and multiple calls were made to law enforcement reporting everything from assault and harassment to sick and injured workers.

Then, I explain why a growing number of businesses are refusing to accept physical cash as payment. On the one hand, the decision--championed by restaurateurs including David Chang and Danny Meyer--could help you to streamline operations and thicken the bottom line. On the other, businesses could be alienating a really important segment of consumers.

Finally, staff writer Emily Canal explains how Sharkbanz, a Charleston, South Carolina-based startup, claims to repel sharks. The company makes an ankle bracelet and surfboard leash that harnesses a patented magnetic technology to drive them away. Last year, Sharkbanz took in just under $970,000 in revenue, Canal reports.
