Legal tender is a tricky thing. I've spent some time a while ago trying to understand how it works, here's my conclusion: "Legal tender" must be accepted for settling the debt. That's it. It means a bartender may refuse to pour you beer if you intend to pay in the form he doesn't like. But once he poured you the beer you have entered the debt for settling of which a bartender must accept your cash. Disclaimer: don't try it in the only bar in your village.
