No, your plan won’t work. If those places could present a dating prospect, it would have worked already. I suggest you take more deliberate action like going to an inexpensive gym like planet fitness where you can go anytime to see different men. If you see someone you like, then match your schedules, make eye contact and go talk to the guy even if he is staring at his phone with earmuffs on. The advantage with the gym is that those people have the discipline to come and you can see what they look like over time and you can approach easily. Men get approached almost never, so they will welcome it and be flattered.
