It's 2019 – why are you still trying to meet women at loud, crowded and expensive bars? There are so many different things that can go wrong. If it's too packed, you could lose a half-hour just waiting to buy a drink; too empty and it'll feel weird and sad, and you won't be able to meet anyone new. Finding someone you're interested in typically begins with you surveying the scene and looking for people who are both attractive and not visibly taken -- or settling for just one of the two. Regardless, what are the actual chances that you'll hit it off? You have to decide whether to go with a stock pickup line or a custom-crafted joke or just a question and hope you picked the right one to pique her interest. And keep in mind this whole scenario is most likely occurring while you're both yelling in each other's ears over extremely loud music and the sounds of other people having a good time.
Daily places where conversations might be possible with women include the laundromat, waiting at a bus stop, shopping (including saying hi to the shop assistant you fancy so much), working out at the gym, walking your dog, clearing up your front yard as she passes by, the library, the video store (you already know her taste in movies), large outdoor events and pursuing recreational/sporting activities.
