You sadly can't trust cashiers to get the DCC choice correct. Even if the cashier is an hourly low wage earner at a chain store or restaurant with no immediate vested interest in whether or not you accept DCC it's still impossible to control the transaction completely. Factor in that there might be language barriers - note the recent example from
jamar - where you might not be able to explain to the cashier that you want local currency. It's just like getting into arguments with merchants about magstripe only cards in EMV countries. It's a losing battle.
You try to stop DCC in its tracks at the time of the transaction. If unsuccessful, you deface the receipt and file a chargeback.
