I live in one of Germany's largest cities, and while this is high, it's not outrageously high.
I guess to me what sticks out the most is the expected 20% surcharge for "tips" (that get collected by the bosses indirectly anyways as they just underpay their slaves enough to make up for the tips they're getting). That's not normal here. You tip for good service, if you pay in cash you also tip to round usually, and you tip if there's some other outstandingly positive thing about it. I really hate how in the US it's become so expected to tip, while also having fuck all protection for the delivery drivers, who ought to get a wage where tips are a bonus, not an expectation. It's just a delivery fee at this point, let's be honest.
Although I will also say that since I live basically next door to a Dominos, I always pick up, which is ~25%-30% cheaper than delivery. Plus no delivery charge, but that's based on distance I imagine.
