truth in advertising

I'm always amused by TV commercials that try to make the truth they are required to reveal sound like a good thing.  I've already mentioned in one of these blogs the law firm that advertises that their charges will never exceed what you receive after a settlement. I guess that's decent of them. Of course any commercial for anything medical will reel off all of the possible negative side effects, up to and including death, in a rapid fire off hand sort of way. Tonight I heard another one.  This was an ad from Firekeeper's Casino. I've been there once and it's an ok place - not Las Vegas but ok. The ad was promoting some big deal prizes to be given our tomorrow. What caught my attention was the phrase "top prize is $50,000 in cash and credits."  That credits part got me wondering - what kind of credits? free stays in their hotel? free meals at the buffet?  some credits on the slots?  how much cash really??
