Throwing a bit of an idea here:

Would you guys think it would be best for int'l travelers to be self-prepared by buying this pocket sized self-inking stamp with a note that says "DCC refused & merchant did not offer a choice"

So when the merchant says "blah-blah-blah" and getting into a time wasting argument with them, all you have to do is whip this out, stamp it onto the receipt and be on your way. Now you have a receipt with that statement that you can just stamp it to show to your bank.

That way, less arguing, less wasted time in writing the whole message down with a pen. All you have to do is say "ok - fine," whip this portable stamp out, stamp it to both receipts and be on your merry way.

Merchants will be dumbfounded on what to do because they don't expect people to have self-inking stamps, let alone a pocket sized one that can be easily whipped out and stamped to the receipts that read "DCC refused & merchant did not offer a choice."

IANAL (I am not a lawyer) so someone with expertise could chime in a better statement that can be used for self inking stamps.
