Regardless, there is a picture of the tag, and there is a statement by the restaurant the valet service is contracted, and that contractor has indicated the valet in question is no longer working for the company.
Sounds legit, but strange nonetheless.
I'm skeptical. I'm sure the tag has the phrase on it, but then so did the dinner check allegedly given to that fraud waitress recently.
When stories like this get widely disseminated to the media like this I tend to suspect that a professional race hustler is at work.
