Dropping The Kids Off

My father-in-law works in the Garden Center at our local SuperCenter. He told me that for the third time in as many months, a female customer pooped in one of the aisles. He said other customers have seen her do it. She doesn’t squat; she just lifts her skirt and keeps on walking. Obviously there’s a mental disorder here, but I’m not sure which one. I hope I never see her or any of her ‘gifts’.
