How would an Irish guy address an older woman whom he is trying to be kinda suave to? I had originally used the word "missus" (as in, "most assuredly, missus," like that), but I realize that probably wouldn't be appropriate, since it's not his missus.
Any ideas? He's sort of old fashioned-ish, but not old. Kinda mid-twenties. Oh, and this takes place in present day America.
