Our Sin City spies spotted Adrian in line at the Bistro Buffet at the Palms Casino and Resort Friday night, where a couple noticed him and asked if he was, in fact, Adrian Peterson. We're told AP answered with his catch phrase (and nickname), "All day."
Peterson asked the couple -- and about a dozen other people in line for the buffet -- if they wanted to join him for dinner ... and then picked up the tab for everyone.
Total cost -- about $400.
If that stupid lockout ever ends ... Adrian will make roughly $10.7 million next season -- so he's gonna be alright.
