Probably not, and almost definitely not at the small retailer. Amex charges are more for the retailer, so they often simply don't accept it.
Other than that, though: I'm not sure how often you even need that $1000 'no questions asked' policy. Second, return policies through the EU market (plus at least one country) are pretty good without credit card protections. It just really isn't a big concern. Finally, the culture around returning goods differs in different areas. Folks here (Norway) seem way less disposed to returning items - especially for simply not liking an item and would rather do some research upfront. (Not working as desired, defective, and things like that are a bit different, but folks still hesitate).
So you don't try to return the item for a refund first?
