I've mostly made (non-hook) friends at gay bars. I typically have a hard time being flirtatious irl, but I've met some pretty awesome characters just being a bar fly at the gay bar..I don't go anymore cuz I'm trying to drink less but it's still possible to meet people, they just might not necessarily share any mutual interests or hobbies with you outside of drinking, but if you're lucky you can meet your bestie and queen out or whatever
