If Avis decides to bill people in their country of residence, it means that AE against DCC protection is bypassed. AE will never know that the transaction was taken place in another country and using another currency.

When I rented the car in Toulouse, Avis billed us in SEK, while we were using Mr. Nacho's DKK CC, which means we got robbed twice. The most annoying thing about this was that I had a hard copy of my contract and I checked that I'd like to be billed in EUR. Avis ignored that despited I complained to their CS.

I also got the BS bill print out at LAX and SFO Avis saying that I was given a choice and I chose to be billed in SEK vs USD. I had never given that choice and I'm not sure this is legal.
