Because a merchant may refuse specific forms of legal tender so long as the debt is cotemporaneous with the purchase. A restaurant where you pay first, then eat, can do this; a restaurant where you pay after eating cannot. In the gas situation, if the payment occurred before pumping, they can legally refuse coins; if the gas was already pumped, technically they could not refuse the coins... but who exactly is going to enforce it? I doubt even most FTers would wait at the store to call whatever local chamber of commerce official might consider investigating...
