Proper dating etiquette is not a thing
No one's getting picked up and dropped off at their house for the “date” and there isn't an implied commitment for dinner. Instead, it’ll be more of a, “Hey, wanna grab a drink after work” type of thing and then you’ll Uber there separately and have to awkwardly find each other in the bar and depending on how it goes, maybe get food after a couple of drinks, and then Uber home separately, and yes he is 100% leaving you alone on the sidewalk if his Uber shows up first.
The dudes (usually) don’t pay
Dudes in the South, and the East, and the North (?): a large majority of them are still paying for the first date. SF dudes, though, not ALL of them, but a LOT of them, don’t feel the need to pay for the entire date. Even if they’re the ones who did the asking out. In theory, this is okay and the girl should probably buy a round or two. In practice, this kind of sucks.
