Give her the chance to respond. If she does not, shrug your shoulders and walk on. Well, yes, I enjoy this particular brand for the tangy metallic flavor of the sauce. For a fellow who finds boiling water a nearly impossible task, I think I do a pretty fair job at making this stuff at least marginally fit to eat. Give her comfort and support, but be extremely wary of becoming more closely involved with her, at least for the present.
Talk is cheap.
Stay noncommital, and let her carry the burden of the conversation. This is a double whammy . On the one hand, she is displaying behavior typical of a giggly teenager. On the other, she is making it perfectly clear that she would be using you only as a convenience, to provide an escort for her into the club, and that any generic male would do just as well. Let her find a more willing victim.
