I'm moving to Berlin in a month for work. I've been to germany before but had a gf then. I only speak a little germany but hoping to learn while i'm there.

Any tips for german girls? Last time I was there I noticed that the girls seem to be less likely to fall for lines, canned openers and have a better BS metre than british/american girls. I remember a couple of times being out with a group and when random guys would start hitting on the girls they would would be polite to the guys but wouldn't give them any chance at picking them up. No shit tests or being rude just pretty much saying nah not interested. And these guys seemed all right as well, no hint of creepiness.
