Every time a saw a local with their wallet open they were paying in US dollars. The pump attendant at the Cadisco in Mount Vernon only has a stack of US bills. Most restaurants would bill in euros and print about 8% more in US. We paid on credit card in euros. Our CC gives a fair exchange and no transaction fee.Our local Chase Bank in Michigan tacks on a ridiculous service charge for euro cash. Super U Hope Estate and Petite Casino Orient were close to par. Hope Market was par AND they gave US change.
