As other posters have already said this is nothing NEW...
We all Know
that trick from "way back when "....when, as teenagers, we needed cigs, beer,whatever!
Some kids just asked strangers in front of the store,but there was always the option of some 18 yr senior/older Bro/sis who would buy them for the younger kids.
Personnally, I grew up in Midtown Manhattan and ,at sixteen, we all smoked during lunch/recess and school breaks on the sidewalk right in front of our school.None of us had any probs buying cigs from the corner Deli.And all of our weekend "parties " included liquor, each one of us would chip in to bring something and I dont recall ever having much of a prob bringing a bottle of vodka or whatever .I know for sure we didnt ASK our parents to buy it for us lol-they wouldnt have and would have freaked too....
Maybe things have gotten alot stricter now...including age limits,in my day we never really got carded, we took the precaution to send the older looking ones..then again it WAS real easy to buy a fake id around 42nd street and WE all had a spare in our bag just in case,but that was mainly to get into clubs(most didnt ask,but with make up etc we all did look alot older than our age).
Buying Ecigs is probably the same deal for today's kids(and by the way how do they manage to buy their cigs beers,liquor or even drugs...???)
Like others though, as an adult I would never take the responsibility for buying anything for a stranger,even less for an underage kid....
