no thanks to you

I cannot thank you for what happened, because you did not cause it.; I cannot thank you for your help, because you did not give it. Bob: Well, despite our previous disagreement, he seemed to agree to all our demands. Alice: Yes, no thanks to you. I wish you'd learn to keep your big mouth shut! Jane: It looks like the picnic wasn't ruined despite the fact that I forgot the potato salad. Mary: Yes, it was okay. No thanks to you, of course.
