I was having lunch at a small café in Berlin city center.
While none of the cues indicated, the owner, and all of the staff turned to be Arabs.
When he found out I work in tech, he told me this area has changed completely in the past three years.
Now most of the offices around his place host startups.
These startups either grow and leave to bigger offices, or die and close.
This poses a challenge to his business, since his customers are rapidly changing.
Another challenge he faces is those startups are not making money, which makes the spending power of the people working there not that high.
A long way to go, Berlin.
