What? Seriously...I still do that. And I still meet people in grocery stores, more so in ice cream parlors, but whatever. And, the whole "dating scene," of giving out your number.
You guys are silly.

Seriously? Whoa. I didn't think people actually worried about those kind of things. Maybe it's because I grew up in a small town, and just recently moved to a fairly large city. But I never use my cell phone, hardly ever. I forget it at home too much, or lose it. But, honestly, I like the whole meeting people at random. The whole lust thing, you know, when you see a person, and it's like..I want to get to know them, and just go and start a conversation about something like, killer whales, or ointments, maybe the weather, you know, something awkward.

When you're young, it's easier because you have common interest with other young people that affords meeting up in groups (or sets) casually to pass time hanging out.
As you get older, your interest become more specific and you're much less likely to hang out casually in group settings. I can be pretty much sure that people in my age group aren't hanging out at the mall...Or whatever... Which makes it tougher to mingle...

I think you're right.
