Parking spot vulture
Parking spot vultures may often converge in droves of three cars or more, waiting ten or more minutes to get a spot in a parking lot. Parking spot vultures do not like to walk long distances or find another lot. They hover in the same lot, and even vigilantly look to see when a person is going to get in their car, so they can grab that spot. This happens in mall lots, supermarket lots, and other tight places where parking is a premium.
Wow. I thought I would never make it to the library. As soon as I entered the lot, there was a parking spot vulture in front of me, waiting to grab the last parking spot. I ended up parking on a side street and walking.
