Kosher Nibbles in JFK's Terminal Four

Recently I was running for a plane at JFK's terminal 4, when I noticed these kosher vending machines. Perplexed I popped in $4.50 and got a perfectly cooked hot dog. Hot Nosh wasn't bad and the convenience factor fantastic. Quicker than I could say shalom, I was heading to the gate wiener in hand. Some of the other food items are onion rings, pizza and knishes. There are about 100 of these culinary cooking machines around the US, Wal-mart and Boston's Fenway Park to name a few. Now if they could only develop a Italian vending machine with perfect chicken parm!
