Bluebird of happiness

I don't think it's a semantic issue, I think it's a real issue, though I think the addition of the salesperson adds a new complexity in that the salesperson isn't making the rules, just enacting them. If the owner of some radical Madison establishment decided to give its customers two payment options - lire, or Madison Hours - I think that would count as "coercion" or at least social manipulation of some variety. Because they don't even print lire anymore. (Yeah, ok, not really coercion because there's the third unstated option of "buy your freakin sandwich somewhere else," which most people would probably take.)
