especially good when that common activity isn't: we're both drinking at this bar
That said, bars are a great way to expand that circle. Dating is just one aspect of socializing. People who go to bars specifically just to "pick up" are creepy.

And it's kind of weird to just go to a bar, alone, and try and find other lonely people to fuck for a single night.
But hey, that's what some people are looking for.
we need a new woke meme to shame people who shit on people who don't have friends
That assumes your friends have friends to introduce you too. Mine almost never have.
