I think I'm going to dine and dash at this local restaurant.
That's not a nice thing to do! Why don't you want to pay for your meal?
Because I know the chef is not paid well.
While it's good that you're concerned about the chef's salary, you still need to pay for the food you eat. If you don't like how the chef is paid, then you should simply not support the restaurant.
That's not right. He works hard and has skill, so he should be making more.
It's nice of you to be concerned about someone's financial situation, especially when you think they are good at their job. However, refusing to pay for your meal won't help him, and it will actually make it worse. If people regularly don't pay for their meals, the restaurant might close, and then the chef will lose his job.
