But you may want to order chicken nuggets fresh

On a Reddit post about items fast-food employees recommend you avoid, Ritch88 says: "If you order chicken nuggets, just ask for them fresh. Otherwise, they've been just sitting in their container in the heat. They have a timer, but nine times out of ten when that timer goes off, people just reset the timer instead of making new ones. This could go on until all the nuggets are sold."

Don't ask for the "secret" Starbucks menu

Customers constantly ask Starbucks employees for the secret menu—but there isn't one. The notion that there's an alternative menu comes from the fact that some creative customers have come up with popular concoctions. But if you want a special drink, tell your barista the ingredients: "I constantly get questions about the 'secret' menu but I swear we don't have one. Just tell me what you want!" says Amelia, who works at a Starbucks in Chicago, Illinois.

The chili is a no-go

The chili at Wendy's may look like a comforting menu option, but not when you find out what it's made from. "[It's] not really a health concern but most people are surprised when I tell them about Wendy's chili," says Reddit user Cozmo23. "The meat comes from hamburger patties that sat on the grill too long to serve to customers. They take them and put them in a bin and then throw them in the fridge. When the chili is made they take it out, boil it, chop it up, and dump it in the chili."
