I don't know where that anger came from, I think 1) because the cashier had tried to talk me out of the refund which was obviously owed, 2) because the customer accused me unjustly for being the cause of one minute's delay, and 3) because these Middle Easterners are always pushy and rude.
Now that I think about it, the cashier shouldn't have tried to talk me out of my refund, the receipt definitely showed 3 items rung up and only 2 in the bag. She was also a minority. They have a very different attitude toward customer service. And if the manager had been Asian, I probably wouldn't have gotten it at all.
By the way, the store was Valley Produce, also known as Valley Marketplace. I know the Zergut brand, I've bought their roasted red peppers. I get a kick out of the brand called Tukas, also from Turkey.
