A: What are the plans for tonight?

B: I thought about going to "the club" tonight, or so?


A: Have you been there before?
B: Of course.
A: (irritated) Oh...well.

To all native speaker:
I am discussing well- and ill- formed sentences in my sociolinguist assignment.

Would you ever use the sentence above or could you imagine that a native speaker would use it like that?
And can I say it's ill-formed because it doesn't obbey the rules of a native-English speaker?

Moreover the second example is grammatically correct. But can I still say its ill-formed, because it wouldn't be used in that context. The speaker intended to say sth like "Yes indeed" but conveyed "Yes, how can you ask me such a stupid question".


I appreciate every kind of help! THANKS!
