This place is totally not a money-laundering operation. It's just through automation efficiencies,…read moreeconomies of scale, and the miracles of the gig economy that they can offer some of the finest thin-crust pizza in Berlin for €4, topped with plenty of top-quality ingredients. If you want a stiff drink, or a carwash, or a happy ending, it's €4. And no matter how many €4s you throw down, nothing, and I mean nothing, will make the surly waiters be anything other than surly. Because for €4, what do you expect?

And if you tip them, I'd suggest you leave them €4.
