I am a male brazilian (born and living) software developer. I'm part of a remote team with people living in Brazil and in USA (born in other countries as well). We've been working together for 1 month.
Currently I am in USA on a business trip to get to know my colleagues working from here.
One day after the work we decided to go out for a happy hour. During the happy hour we started to play some party games (let's say table-tennis) and I got a match against one of my female colleagues (which is also our team leader). Since it was our first match, we were not sure about who was supposed to start playing. I tried to be polite, so I said:
"Ladies first, please go ahead!"
Briefly after she looked at me and said that this is a very rude thing to say in USA. I felt really awkward and promptly apologized to her. In Brazil usually it is not a rude thing.
I know that the "ladies first rule" is something that may sound rude in some cases, but in this situation in particular I was just trying to be polite with a colleague that I hold a huge respect.
Question: How rude is "ladies first rule" in USA?
