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.
