Gotta agree.... you just found a run of bad flunkies.... I have never been to a Sam's that didn't keep butts and briskets on hand in spades.
Lots of folks actual cook them in the oven like a roast.... I know it is a wild concept... what what season are they referring to!
Did you get to talk to thier butcher, or just a lackey in a white jump suit...
