Minutes after a United Airlines flight attendant announced over the P-A system that a small selection of sandwiches and "snack boxes" would be offered for sale, the food cart came rolling down the aisle in my direction.
"What exactly is a snack box?" I asked the flight attendant.
Without blinking an eye, she replied, "It's basically a lot of junk food in a bag."
Actually, there was a small packet of trail mix tossed in there as well, but, otherwise, she was telling the truth.
