How can I get a female minister in a high-end hotel?

You know, many people who work in the service industry (not the porn industry) are forced.

Classes are irregular, even for ministers.

I have to work overtime when I am busy.

It is when others have a holiday that they are the busiest.

It's easy to talk to them.

Go there and eat more.

Give her more hints when you "mix" with her.

Women are naturally sensitive to such hints.

If there is no obvious refusal, ask her out boldly.

In the future, you have money and a car, so you can pick her up after work.

The latter thing is logical.
