Hi. I'm not sure this is the correct forum but could really use some perspective from Germans and those who travel, know, interact with Germans.
While out at a restaurant in the U.S., the waitress returned to the table to clarify a custom order. My brother's girlfriend, who is German, responded to the waitress in an extremely rude, obnoxious, and condescending manner. It was nothing like I had ever seen before, everyone at the table was aghast and the poor waitress was shocked and just turned and left. As it turns out, the waitress handed off the ticket and her manager took over. I called the gf out on her behavior. She didn't see anything wrong with her behavior and in fact, said that the waitress was stupid and should not have even asked the question that she did.
The gf tells me this is a cultural difference. I say bs, this is just bad behavior and you can't blame a cultural difference. I refuse to believe that what I witnessed was a "German" thing, rather than someone who just does not know how to treat people with courtesy and respect. Oh, when I suggested that treating people nicely gets better results, she disagreed.
Please help!
