Writing prompt: what happened?

Cafe in Rabat, Morocco

While wandering through the streets of Rabat in Morocco we happened upon this lovely looking cafe.

Not a single customer despite the establishment being open at the time, and with a wonderful view over the river estuary and the Atlantic Ocean.

I wonder what happened?

Writing prompt: let your imagination run wild with the possibilities. What happened to all of the customers? Is there any significance in all of the furniture being painted blue?

Good writing.
