Just to share, you guys might use that as an approach. It came to me by complete chance and I was genuinly offering a help.

I was at the vafe, I saw a nice tall well-groomed asian girl with other two asian chicks on the table.

I saw her having a look and smiling at one guy sitting in the cafe. I though she was interested in him.

After I have finished my coffee, I approached the girl on her table with her friends and asked her if she likes that guy becasue I saw her smiling at him. "I can talk to him if you like" I told her. She told me that she was not interested in that guy, she thanked me then I walked a way.

However, she was very glad that a man came out of no where and offered to be a wingman for another girl. I think You might use that as an approach and I think it is very sweet to offer help. But I was very genuine, I had no interest in the girl I just wanted to help her out.

Just to share.
