Whenever I swipe or insert my debit card into an unfamiliar device, I usually give it a good glance over, and poke and prod it every so subtly. Once in a while, I get an awkward look from someone I'm with, or from the cashier. But there's a good reason for it. I'm checking to see that everything is the factory-default, so to speak. And after Safeway's most recent announcement, you might want to do the same.
