Do girls find it weird/unwelcomed to be approached by a lonely guy in the bar/club?

I'm new to the night scene & non of my friends like/cares about it. I'm not exactly sure how I ended up becoming friends with these people, but most of my friends are married "I'm 22". I honestly don't think I'll like it, but I love trying new stuff & this seems like a good/fun one to try

Besides the obvious advice of finding new friends, any thoughts/advices on the solo night game?
