How’s this for enterprising? In case you haven’t heard, you can once again brings small containers of liquids and gels through airport security as long as you put the containers in a clear plastic bag. Well, while I was going through security this morning at Hartsfield-Jackson Airport in Atlanta, I noticed that a steady stream of people heading from the security table (set up at the entrance to screening area) over to a nearby shop. As it turns out, these people hadn’t brought plastic bags for their stuff, and an enterprising shop owner was selling small Zip-Locs for $0.50 apiece. Mix in a captive audience, and you’re talk about a very high margin business… You can buy a box of 100 bags for a couple of bucks (retail), and then turn around and sell them for fifty bucks! He was probably taking in more on bag sales than on all other sales combined.
