I round the corner into the parking lot of the little family-owned grocery store by our house. I check my list one last time before going in, planning the quickest route to get my things. Inside, I grab a basket and am off on my journey. Power walking through the store, I fill my basket with fruit, veggies, lunchmeat, meals for the week, and some other odds and ends. I don't have to wait at the checkout line (yes!), so I pay for my things, grab the bags, and head back out to the car. I strategically place them in the trunk to avoid them all rolling around, and head home.
After bringing the bags inside, I begin unloading. Lunchmeat in the fridge, pretzels in the pantry, frozen chicken in the freezer... wait... where's the frozen chicken? Frantically searching the bags and coming up empty, I run back out to the car. Nothing. Back inside, I check my receipt. Yes, I bought it. Where is the chicken?!
Knowing that this isn't the first time I've left a bag at the store, I immediately think back to the person bagging my groceries. Did they fail to give me a bag? Did I forget to pick up the bag? Either way, I get back in my car, drive to the store, and there inside, sitting at the customer service desk, is my chicken.
