Something about eating Muncheros made us feel sophisticated. We don't quite know what it was. As adults, we're well aware that they were just another cleverly-packaged variety of chips, but they were different to a child's eyes.
Maybe it was all down to the flavors. We weren't used to anything as exotic as lime and chili flavored chips back then. As far as we were concerned, these were the chips that our parents ate at dinner parties.
