I didn't get the guy a refund. Worked in the service industry, hated people like this. He didn't bring the toaster oven, and had no proof of purchase? Somebody's just trying to work the system. If he wants his money, he can do it right, nobody's going to work off the clock for him, especially when they need their time off to contact their family.
Plus, I don't even think he was the same guy.
