Good idea to pay in local currency versus dollars

There was a comment in the June 2018 issue from someone who got stung by paying in dollars as opposed to euros, and being stung by a double currency conversion charge. (See P.48 of the print issue.) This is old news but it bears reminding people that you should pay in the local currency when using a credit card. Our experience has been that we have been asked if we wanted to pay in euros (or whatever the currency is) or dollars. This poster paid 4% more on one charge and 3% more on a second. His warning was if you have a credit card that doesn't charge a conversion charge, pay in the local currency. This is what we have done for MANY years.
