I usually just pull out a different credit card, and then take the card that didn't work out of my wallet when I get home.
Sometimes I might get around to calling my bank (somewhat depends on my perception of how long their customer service is going to take to fix the issue), but it's faster for me to just replace that card with another card from my collection of cards (I've got too many cards to keep them all in my wallet at any given time).
The last card which was incorrectly flagged for suspicious activity probably cost that bank several thousand dollars in foregone interchange fees.

This is a real and common problem for banks/card issuers, who tend to be obsessive about keeping genuine transactions declined to a minimum for this reason.
Blocking all fraud is achievable, but it would come at the cost of many instances like this.
