Man arrested at Best Buy for using $2 bills

[Bob]

Now correct me if I'm wrong, but isn't there a law in the US saying that all legal tender must be accepted for payment of a debt (not trading in a contract, paying what you owe someone already) and if someone refuses to accept legal tender then the forfeit what they're owed. Or am I making that up?

Doesn't he have a pretty blatant false arrest case there? both BestBuy and the local police deserve to get legally flattened for this.
