Yup, Ms. Grace,
That guy had seemed to have lack of social skills. I mean, whatever happened to a hello?, how are you?, and make some polite small conversation about the airport, traffic outside, accents of people, destinations he's about to go too?, and how different it might be?, get a feel for you first, then maybe, just maybe, he can invite you to the lounge, if you obliged. Sounds too much like a wham, bam, thank you mam type.
