Berlin-Kağan Sümer is wearing black: baseball cap, surgical mask - and a T-shirt with the white logo that has come to symbolise the strikes at the young, yet already controversial grocery delivery service Gorillas. In a video that did the rounds on social media, the founder and CEO stands outside the company's Schönhauser Allee warehouse. He's encircled by outraged employees lamenting working conditions at the company.
"Take a deep breath," Sümer says.
