willing to ....

There's a frozen delivery scheduled to arrive tomorrow.

--Frozen delivery? Okay. I'm willing to stay home and work online tomorrow. Have a good time with your friends. I'll go to the gyudon shop for dinner.

I'm not a big fan of spacy food. But since we are in China, I'm willing to give that a try.

I'm willing to pay for experience and a good meal.

Would you be willing to work abroad?

Of course. I've always wanted to work overseas.
