The story about the Tesla took place at Four Winds Casino New Buffalo, which is in Michigan, not Las Vegas. Legally speaking, it is a sovereign nation so I would not put much trust in "local authorities" to protect consumers. Further, although Nevada does have a gaming commission, there are still plenty of "scams" and questionable promotional tactics used by companies both inside and outside of the casinos. Time-share sales, for example, are big business in Las Vegas.
