Shy guys if your crush asks you for a favor?

Do you do it regardless? Tell her the truth if its something you can't do but make it clear you would do it otherwise? Say no? What if its just any girl is it different?

If you couldn't do it would you feel the need to explain why so she doesn't think badly of you? Or just say no?
