Can you imagine a company treating you like this in person?
Like say you walked into Wal*Mart and selected some merchandise from the shelf, then walked to the register and paid using a Vanilla Visa card, as you noted there was a Visa sticker on the door when you entered. While you are picking up your bag from the bagging area a security guard roughly picks you up and throws you out the door and tells you to never come back. You ask why but their only response is "You were being suspicious."
I have actually seen this multiple times - a very common thing, at least in the US, is using gift card magstripes for cloning stolen card track data onto.
This is mostly irrelevant in countries that use chip and pin.

The customer is left bewildered, angry, and hurt.
