Taking it a step further: After hearing the parting remark, you think he/she’s not really your type or maybe they could be and you haven't until that moment figured it out. Should you say something or pretend you didn’t hear it, the next time you meet? Who knows it might lead to love. Without the surreptitious remark you would have never had a clue.
Call this a cute communication instead of a cute meet, although you may be meeting the person for the first time as more than an acquaintance.
