If you work in fast-food, then you no doubt have menu items you'd never recommend and other dishes that you think are totally overrated and/or overpriced. At Dunkin' Donuts, we've figured out super smart money-saving hacks. But what about all the stuff our DD coffee pourers and sandwich makers aren't telling us?

Thanks to a few first-hand accounts from former employees, we finally have answers. Not only are there items to avoid, but there are also tricks to making sure your order comes out correctly.

1. Keep it short and sweet at the drive-thru.

To start, "we are on a timer," Emily Daigneault originally wrote on The Odyssey. "Every Dunkin's success is measured by how fast their drive-thru is." This means you should curb your massive coffee order for the office and get in line inside instead — it will keep things speedy for both you and the restaurant.

2. Listen carefully.

If a DD employee repeats back your order, pay attention. No one wants to get the wrong coffee. And no barista wants to start over on a busy morning. "This way we can make sure you get exactly what you want!" Daigneault points out.

3. You can't get "half" cream or sugar.

According to Daigneault, every Dunkin' locations uses machinery to dispense cream, milk, and sugar. If you ask for half cream, you're not going to get it. "It's a machine with predetermined settings. Same goes for sugar," she wrote. "Don't be mean about it, we're just being honest."

What's more, there's a standard for cream and sugar. In a small coffee that's two each, medium is three each, large is four each, and extra large is five each. If you'd prefer a different ratio, say it!

4. Bagels and sandwiches are automatically toasted.

This goes for English muffins and croissants, too. Be sure to specify if you'd rather it not get warmed up.

5. "Regular" isn't a thing.

It has too many different meanings depending on the individual. "A lot of people tend to order their coffee regular, then get mad when we ask exactly how their coffee is," Daigneault noted. For some people that means hot and not iced, for others it means the standard coffee blend (versus hazelnut or dark roast). Instead of oversimplifying your order, get specific.

6. The "eggs" aren't totally real eggs.

The brand's enhanced egg product contains egg whites, egg yolks, soybean oil, water, corn starch, salt, natural flavor, xanthan gum, cellulose gum, and citric acid, The Street reports. This is because there aren't any flattop grills for Dunkin' to cook fresh eggs on the spot. Instead these pre-made "eggs" are warmed in a convection oven in seconds.

7. The Big N' Toasted is horrible for you.

Packed with 14 grams of saturated fat (that's 70 percent of the daily recommended value!), 1,230 milligrams of sodium (that's 51 percent of DRV), and a mind-blowing 345 milligrams of cholesterol (a stunning 115 percent of your DRV), Mashed reports. Holy sh*t.

8. Coffee coolattas are devious, drinkable desserts.

One former employee explained to Mashed that the line of coffee-swirled Coolattas are "tricking overheated commuters with a sweet tooth into slamming a full-on dessert under the impression that it's coffee." We can't say we disagree: The frozen drinks, like Starbucks frappuccinos, are ridiculously sweet, loaded with syrup, ice, and cream — not to mention topped with a bunch of whipped cream. They're more like milkshakes with a splash of coffee and are also super-packed with calories and saturated fat.
