cart vulture

A person very eagerly awaiting to take your cart at a shopping mall or grocery store, to the point of uncomfortably standing beside you in the parking lot and starring while you put your groceries in the car, just because they either want a motorized cart with a full battery , or a tiny shopping buggy.

"I could barely get my groceries in the truck, before the cart vulture wanted to swoop off in my beeping chair".
