For the record, I didn't know which flair to use for this topic, so if this isn't it, I'm sorry.

Context as short as I can, the point of this post is at the bottom:

Last night I was at a bar being present for a pool league match, and when I was told that I wasn't playing, I began to just hang out. I came across this group of four girls playing darts. I didn't have any serious intentions, I was just trying to hang out, and I watched them and interacted with them. I asked for their names, to which only one of them gave me her name (let's call her D), the rest ignored me while they were playing darts (it was a loud place, so I didn't think much of it). I did offer drinks, but when I did, all of theirs were full, so it was declined. One of them did explain that all 4 of them wanted to just hang out with each other alone, so I respectfully withdrew to hang out in other places in the bar.

When it was time for me to go, I said goodbye to everyone I knew and the girls. I had said goodbye to D first, and the topic of contact info was brought up and we mutually agreed, but it was interrupted by one of her friends who then straight up asked "are you going to be weird about it?" I didn't address it, but it did feel quite rude in all honesty. I then just left after one of the other friends tried to lighten up the situation by fist bumping me. No phone number or anything from D.

I completely understand the social dynamics of a friend group in that they try to protect themselves a lot, and understandably so because THERE ARE CREEPS OUT THERE.

Point is what I ultimately want is to at least find a way to address rudeness from someone in a friend group without having to escalate tensions beyond being cordial (or at least without having me looking like I am being uncordial), hence maintaining frame.
