What should I do if I see a female webmaster in an Internet cafe?

It depends on your personality. If you are brave, go up and ask for your phone number, except that you are handsome and rich, and the probability of failure is 99%.

I suggest you take a detour, surf the internet for a while at a fixed time every day, chat with her when you turn on the phone, praise her, or say two jokes.

In the process of surfing the internet, buy more snacks and drinks, contact more and talk more.

Remember, usually serious girls don't like men addicted to the internet, so you shouldn't spend too much time surfing the internet.

After a week or two, she will basically have an impression on you. Your greetings can be changed to "Hello, meet again" and "Why are you on duty again? It turns out to be fate".

At this time, you can consider asking a name or something. In case she doesn't go to work one day, you can also ask her colleagues where she is. In two or three weeks, you can consider going out for dinner and shopping.
