Berlin Mitte: Agree, yes, atrocious service, many arrogant people, no credit cards because of tax fraud (Lived the startup life in Berlin for 20 years, "Monsieur Vuong" was IMHO the worst for service and arrogance - but then there is "Il Pane e le Rose", lovely people, went there for 20 years, or "Restorani Tbilisi", my favorite restaurant in Berlin, most excellent food and service).
Nice city somewhere else: No. Here in Stralsund we go to 5 restaurants regularly. All are nice, have excellent service, people are friendly, prices are fair (But I so miss Georgian food).
I agree with you. Haven’t had very bad experience with service.
I for example am perfectly ok with flagging down a waiter to order extra drinks.
The US make me feel uncomfortable with their almost obnoxious wait staff asking you 100 times if everything is ok…but hell breaks loose if you’re done with your meal and you just wanna sit with your buddies and have one more drink or finish your beer.
Then wait staff manages to make you feel very uncomfortable in my opinion. Much worse than default German service.
