One of the members of our friend group never buys a round. She's happy to accept a drink when someone else is buying, but never reciprocates, apart from one time when her best friend called her out on it. At which point she claimed she wasn't thirsty.
Our friendship group normally meets in pubs for lunch/birthday etc drinks but now it's got to the point where she sits drink-less (she waits to see if someone will buy her a drink) because everyone else has wised up to her . It feels awkward and is in danger of spoiling the vibe when someone gets a round in but misses her out.
So should I have a frank talk with her, and what should I say? This may or may not be relevant but she might be on the spectrum, so not very good at social cues. But she also might just be very stingy (or both). She's not poor btw, quite the opposite.
