A prospect I have is a waitress at "special events", galas and stuff like that. She invited me to one of the events she is doing which is a little weird and definitely friendy, so I am unsure exactly how to react. My obvious options are (1) ignore the invitation and fail to show up, (2) go stag with a male buddy to the event, and (3) bring a female date, (which would put her in the position of serving me and my date). I think she is expecting me to do #2.
The tone of her invite was "friends group" kind of thing, but there is an undertone of sexuality. Like I think she quit seeing the stoner she used to hang out with when I expressed my interest. She is at that age (~30) where girls get serious about marriage.
