If you call the police they can send policemen.
Since it's a constant issue maybe you try to raise it with the baladieh.
Maybe you can use some contacts.
I think you should try various options but be ready for some rude responses.
Let us know how it goes.
Also it might be a good idea to try to sort it directly with the cafe. I know it sucks, but at least you can say that you tried when someone asks you.
