By my calculation, you were scammed for about 4.8% = (70.42-67.19)/67.19, assuming your currency conversion from GBP 40 to $67.19 was correct for that day. That seems typical of the many reports here (and, by the way, higher than even the AMEX 2.7% FTF).
I don't recall if I was given a choice the one time I was DCCed at a hotel a few years ago, but I probably thought, "Oh, that's nice. They converted to dollars for me." Ignorance is bliss...
