Job: Is it risky to deliver food until 22:00 (10pm) nt Berlin or am I just paranoid?

I have a bit of a bad feeling everytime I deliever food with a van late at night (until about 22:00) at some places in Kreuzberg (Kotti, Görli), Friedrichshain and Mitte. Is it risky or am I just paranoid and shouldn't worry about it?
