Ehhh I don't think this is too farfetched. Not all young people talk like this but some sure do. The no disrespect is kinda odd though, but may just be referring to him asking you a question out of the blue.
But yeah I wouldn't respond just on the basis of I hate people asking if they can ask me a question but not asking the question. Like well you already asked me one question and now I need to wait to hear the second one?
