Today, I tried using a coupon to "buy one drink get one free", but when I handed it to the check-out guy he said it expired. Suddenly, my 12-year-old sister whips something out of her pocket. Looking around, she slides the paper over the counter, discreetly whispering, "Maybe this will, ah, change your mind." The guy took a look at it, then after looking around, slyly slid a small wrapped cookie over the counter, giving it to us for free. As we left the store, I asked what she gave him. Turns out she just grabbed the first thing that she could reach....which was a flyer for senior citizens violin lessons. MLIA.
