Safeway Backpacks

We're at Safeway in the checkout line. Our cashier gets a look from his manager, he sighs and with puts on a small backpack. Apparently Safeway is doing a promotion of some sort and the backpacks are part of it. I'm not sure why, and I wasn't going to ask. He looks at me and says, "Eight years in the military carrying around the rucksack, weapon, the whole thing. I never wanted to wear another one as long as I lived."
