1. The "secret menu" at Starbucks. 

Many Starbucks workers advised not to order off the "secret menu" — because it doesn't exist. 

"If you want a snickerdoodle or Nutella Frappuccino, know the base drink and the modifications, and order that," says barista stac52. "If you just say the name, it's up to the barista to come up with what's in the drink, and it may not be what the last barista you ordered from put in there."starbucks frappuccinoGabrielaP93

2. Chipotle quesarito. 

This secret menu item is a huge pain for workers, writes Ssutuanjoe

"When customers order them, every employee in the restaurant hates you," he writes. chipotle quesaritoImgur/Reddit

3. McDonald's Mighty Wings. 

"They are specialty items that are made by request, so we have to go to the freezer, set out a special area in the deep-fryer (The spiciness of the wings can mess with other foods) and they take FOREVER to make," writes kalib97. "If you're fine with waiting 7 extra minutes for your order, go ahead and buy those Mighty Wings."McDonald's Mighty WingsWilliam Wei / Business Insider

4. Gargantuan "with extra everything" at Jimmy John's.

6. A bread bowl of broccoli cheddar soup at Panera Bread.

7. Late-night pizzas. 

"One word of warning: do not show up 30 min before close, drunk, and order a double meat lover or ask me to 'hook you up' with double toppings," writes former Pizza Hut worker TheMightyFSM. "When dealing with more than 5 toppings the oven will not cook your pizza all the way through and I will laugh as you attempt to eat your pile of half-cooked dough."pizza hut stuffed crustBy punctuated on Flickr

7. Ridiculously modified food. 

"Restaurants make food the way the chefs and general managers want to, not the way you do at home," writes diner employee cravecase. "Please trust that the people you are paying to cook your food, that they are doing it right."barney greengrass eggs loxPaul Lowry/Flickr

8. Loaded-up Subway subs. 

"When you order all of the veggies on your sandwich (especially flatbread) we want to murder you," writes Digital-Caffeine.

10. P'zolo at Pizza Hut. 

"Subs take a lot of time and extra work, so workers don't put much effort into them, writes pottymouthgrl. "They mess up the flow when it's busy, and if we're really slammed, then we will probably be 'out of buns.'"p'zolo pizza hutPizza Hut
