You are looking for a birthday gift for your best friend. unfortunately, the item you wanted to buy is out of stock. "hello," a store clerk says. "i see that you're looking for the new album. we recently sold out of that, but we have another band's album here that is very similar. you should really buy this one right now. if you don't, you'll probably find that there's nothing to give your friend at all! " what fallacy did the clerk just commit?
