as tempting as it is to keep filming and giggling, they really needed to step in and stop what could have been quite dangerous! at least they eventually told her...
I'm sure the video is real... likely not her car... borrowed it to show a house or something and wanted to return it "full"...
I'm never amazed by what people don't know any more. I can't go through life being flabbergasted all day at the ignorance of people. occasionally, it is definitely good for a laugh though!
