I had a friend who tried the same thing, bars and such. He didn’t try anybody in his friend group and he was more ir less isolated at work, so there was no real pool of people to look into. I suggested getting a cheap seat at the ballpark and he balked saying he didn’t like sports. I told him even if he walked the concourse, there were still folks he could interact with. He ended up finding some girl who was an actual prostitute and got him hooked on drugs.
No, once he kicked his heroin habit, he kicked her to the curb.
