Okay, all clear now, it is over DCC and the fact that the cashier didn't ask for it clearly from the customer.
Despite the above 4% is an amazingly low (good) rate for DCC ... ! Maybe that's why nobody notices it and they can get away with it.... lol
So from now on asks specifically to be charged in local currency (not DCC), problem solved... (well, for those who know, unsuspecting tourist, tough !)
I recall the incident many years ago when a thief stole a credit card from my wallet. I was at the gym working out, and my clothes were secured in a locker in the locker room. A thief entered the locker room and picked my lock to open it. My wallet contained a fair amount of cash and many credit cards. But the thief never touched the cash and he took only 1 card. Consequently I never noticed anything amiss.
It wasn’t until a few days later when I wanted to use my card at the gas station that I realized it was missing. But even then it never occurred to me that the card could have been stolen because I knew that the card had been secure in my possession at all times. So I assumed that I must have left the card at the last place where I used it. But when I returned there to hopefully retrieve my card, they told me that they did not have my card and nobody had reported finding it. So at that point I just assumed that the lost card would eventually turn up in the washing machine or under the car seat or some other stupid place like my lost things usually do.
A few days later back at the gym, I overheard a couple guys talking about how the locker room had been hit with a bunch of credit card thefts the previous week. They explained that the thief would enter the locker room, open a locker by picking the lock, and remove just 1 credit card from a wallet so that the missing card would not be immediately noticeable. Upon hearing that of course, I immediately realized that I had been one of the victims, and I called my bank to report the card stolen. But by then the thief had racked up thousands of dollars in purchases at various merchants in a nearby state.
I realized then how smart that thief was. If he had taken my cash and all my credit cards, I would have immediately noticed and called my credit card companies to report the cards stolen. He likely would have had little if any time to use my cards. But by not being greedy and selecting only 1 card, he knew that this would go unnoticed for a while – long enough for him to rack up some hefty purchases.
The clever scammer is measured and understands that his scam will be short-lived if he is too greedy, particularly if it involves repeat customers. And before certain members here jump all over this post with outrage and indignation, let me state that I am not accusing anyone of anything. It is entirely possible that the implementation of this DCC scam on multiple consecutive purchases by different cashiers for many weeks was simply employee or machine error. And as I stated before, I probably never would have noticed this surcharge on my purchases if it were not for the fact that I was trying out a new credit card and wanted to be sure that the bank was giving me the proper exchange rate. But regardless of the intentions here, I am nevertheless disappointed in the way that I was treated when I returned to the store to seek an explanation. I am also disappointed that despite all the controversy on this thread, nobody representing the merchant has come forward to offer an explanation. But I am grateful that based on the information in the recent post from Chico bill, this complaint has apparently been heard and the problem has been corrected.
