You were working the cash the grocery store and I had a few bags' worth of stuff. I joked that I wish I had a car, and we got to talking about how it sucks to carry groceries home. After, as I hobbled across the parking lot toward home, I heard you call after me and turned to see you running after me with my credit card in hand! You tucked it into my pocket and ran back inside so fast I barely had time to say thank you. I probably wouldn't have noticed I'd forgotten it until the next time I needed it, but thanks to you I know to be more careful with it from now on! I hope I can return the favour someday! —Forgetful Pedestrian
