So forty-five minutes into her shopping, she's sitting in the chair near the cash register, looking at the trays of earrings. I'm at the computer, and I realize that she's gone quiet. Too quiet. I look over, and she's slumped in the chair, and started to tilt to the side. I scoop up the phone (in case I need to call 911), and am on my feet to check on her vitals, asking loudly if she's okay. Which wakes her up. I think she was a trifle embarrassed to have dozed off like that; and I didn't point out that she nearly had an ambulance dispatched. Moral: Don't fall asleep while in ill health, people will assume the worst.
I'm just glad this event wasn't any more interesting than it was.
