Cell Phone Culture (File Under Me As an Old Man Yelling At Kids to Stay the Fuck Off My Lawn)

I grew up in a world wherein if you told me there were places that you could call up a restaurant and they'd bring food to your door I'd think you were fucking crazy. These days, in large apartment buildings, if you don't have a buzzer you just tell the delivery guy to call your cell when he's downstairs, since he has a cell phone as well. I relish looking forward to scaring the next generation by saying that there once was a time during which the restaurant would hafta call your landline to tell you the delivery guy was on his way, meaning I'd hafta check downstairs after about ten minutes and then wait around for him...BOO!  I mean, can you imagine?
