All girls here, including me, learned English in school many years ago. Many of us do not remember it at all. We have to use google translate to communicate with men. It is comfortable to translate text; I can copy your message and put it into google translator. Then I understand meaning of the sentence.
However, when I will go for meeting, I will not understand you. It is difficult to understand real speech. When native speaker talks it is very fast for me. I cannot understand main thing in conversation. In addition, I want to know many things about man. I want to ask many questions and understand answers. I could not use google translate, when person will talk in real life. Therefore, I need help at least on the first meeting. That is why we ask about translator.
Ask yourself: do you want that woman understands you well? Do you want to understand woman well at the meeting? I think that answer will be - yes. So it is normal when translator will come at first meeting and help us. Do not ask girl “Why do you need translator?”)))) I think that all men will understand me and try to make comfort meeting with their beautiful halves. )))
I wish you splendid meetings and understanding in all questions!
