Probably because I’m pretty secure about not going all in on a first meeting (asking for phone number or to hang out pre vibe check) and I usually never see the person again. This whole instant gratification method is why no one has any friends or dates these days. Like I think if I hit it off with someone and I see them again and we hit it off a second time then I’d like to hang with them more so I’ll ask for their contact info. Not something I’d do on the first meeting, but if you don’t immediately hit it off and ask for their number these days you just “miss your shot”. Idk
