Credit card thief?
Just had 2 purchases at the deli using different credit cards, first was a common Wells Fargo one and the 2nd was a Chase sapphire reserve. After the sapphire reserve card was swiped on the POS for the purchase then the cashier brought it to a separate card reader and swiped it again quickly. That gray color suspicious card reader was nothing like what I had seen before, no screen nor a button, with a wire idk where it connects to. Didn't bother to argue with her, wouldn't believe whatever she would say though. Called the bank immediately.
