The picture shows a man who is apparently sitting in a café or restaurant with his laptop at a single seat with a glass table. He is sitting at the edge, right next to a window front that can be seen in the background. He is wearing a grey flowing jacket and a simple black jumper underneath. He has short brown hair and wears square black glasses. He is holding his mobile phone to his ear with his right hand and appears to be making a call as he smiles broadly. His left hand is placed on the touchpad of his laptop.

The picture was taken diagonally upwards towards the ceiling of the office space. As a result, you can see the dark brown ceiling with white ceiling elements and silver pipes stretching across the entire ceiling in the background. In the lower left part of the background, you can see several office desks and glass partitions. You can also see a man sitting with his back to the viewer. On the right, in the background, you can see more glass partitions, more office desks and chairs and a white wall with two large bright windows. The entire background is blurry, as the photo focuses on the man sitting at a white office desk with a light grey laptop in the foreground, from which the photo was taken. The man is wearing a light blue shirt with a dark blue jumper over it and black square glasses. His hair and beard are greying, and he is smiling as he talks to a customer about their Energy-Management-Minute-Review provided by ista.
