TL:dr drunk dude cold approached women, gets shut down

OK so I'm drunk as I type this but I want to express this while it's still fresh on my mind

So I was at this bar tonight. Just myself as I was dropping off my mum for a dinner with a friend and I had time to kill. Couple beers in a few women walk in. Mid-late 20s(I'm 19). I'm shit faced so I approach and ask if I can join (kinda just sitting down not looking for a response). They say "yeah of course" and we talk.

Theyre from a cruise or whatever, I was too shit faced to listen. But as the night went I just sensed they weren't interested. None of them giving me any eye contact/making any conversation.

I just felt like I was interjecting everytime I talked and I was too drunk to really "feel the room". All in all they just weren't feeling me u know.

I wasn't expecting them to suck me off right there, but atleast for them to be accomadating of me idk

I honestly don't know how long I was with them, maybe an hour, before their friends say "let's go to the supermarket" and I was left to eat my pizza and drink the last pint of my craft beer by myself. I wouldnt say I said anything stupid per se, it's just I don't know if what I did was autistic. Is it too weird jointing into new groups?

Not really one question I have for u guys, more like what could I do better. I like joining new groups of people and meeting new people so I'd like some tips to keep in mind next time I do it.

Should I have kept to myself, were they just being nice by not saying "no u drunk cunt we don't want u to join us"?

Thoughts that plague my mind

On a side note, got pretty drunk and made friends with the bartender/manager, and he offered me a job interview. So one positive to take away lol
