It's been a few decades but I remembered working the grill at Wendy's and sometimes we were told to throw a slice or two onto the grill then top the burger once they melted. So you diners got cheeze and extra beef fat. We weren't allowed to scrape off the fat from the grill because it kept the burgers "moist".
Wendy’s breakfast is OKAY at best. First time having it I wasn’t blown away by it. I got the honey butter chicken biscuit sandwich and was underwhelmed
Wendy’s cookies are normally baked fresh in early afternoon. The breakfast is the best at opening because literally everything is fresh. The coffee is always trash.
