I wonder why no one suggested yet to just go to a group that looks cool and say "hey, I've come here alone and want to meet people, would you mind if I join you?" and the answer will almost always be a resounding "yes" and you will be adopted.
I really don't think that would work, it would be very awkward forcing something like that. Unless everybody is absolutely smashed you could maybe have that but it would still be not great
It really depends on the people, personally if the person gives of good vibes I would 100% let them join because we're all there for a good time and to have fun and be jovial
This was my go to method of meeting people at college parties (which is admittedly a slightly different environment), but it never failed to work. Long as you aren't giving off "creep" vibes most people are also down to meet new people
I can almost see how they come to a group of people and challenge the biggest dude to a challenge of alphas to get al feeeemales, or whatever latest brainrot image board convinced them the human interaction is.
"Hey, I've come alone and want to meet people, mind if I join you?" Also works a lot better for lonely/other asocial people in the bar, since asking about their day right off the bat can make them feel awkward
