> I've met many people in coffeeshops, made friends, even been hit on fwiw
I don't think anecdotal evidence would be very convincing in this case, since your success (there has to be a better word for this) would largely depend on your percieved attractiveness and/or approachability. The setting might not play as big of a role as you think it does.
> I'm surprised you find it to be an insurmountable challenge.
I'm not GP but I didn't get that impression from their comment. I agree with them in that the meeting-people-at-coffeeshops is an overused cliche that was popularized by pop culture/media with lower chances of success.
I can tell you as an extremely socially anxious person I’ve actually done it myself. There’s power in clichés.
It sounds really weird to write it all out but this is just how it works. Familiarity leads to social interaction and you need to be consistent about it if you don’t want it to peter out.
It should also be said that if someone is not comfortable with any stage of this then it’s best to leave them be.
