My problem with this kind of thing comes up at places like Walmart or target where I get some random item that is age restricted that you don’t necessarily think about being age restricted until the machine is yelling at you.

Kind of wish it would take the rest of your shopping cart into account. The guy buying fishing lures, dish soap, a box fan, and some groceries is probably not a teenager who’s going to go home and huff that canned air duster.
