We're usually in a hurry when we order fast food and not always looking for quality.

Fast food used to be a more inexpensive option, but not anymore. The average combo costs almost 15 bucks.

The global fast food market is enormous. It's a 650 billion-dollar-a-year business—that billions with a b.

That's why every busy highway is lined up and down with fast food restaurants. From burgers to tacos to chicken, there's something for everyone.

Yahoo! Finance decided to look at the ratings of America's fast food joints and report on the 13 worst.

Here's how they crunched the numbers.

For this article, we compiled a list of the 13 worst-rated fast-food restaurants in America according to Reddit. We went through multiple Reddit threads and used search terms like “worst fast-food in the US”, “worst fast-food chains in America”, and “America’s worst fast-food restaurants” to find relevant threads.

There were some real surprises on this list.

Taco Bell came in at number 12. This was surprising because my local Taco Bell is jumping around the clock.

The main complaint about Taco Bell was that it made reviewers sick. I'm not going to argue there. Haven't we all made a late-night trip south of the border only to regret it the next day?

Say it ain't so. Sonic? Yes, America's favorite drive-in landed in the top 10.

With the cool drinks and tots, what could be wrong with Sonic? However, Reddit users complained that the food was too greasy.

Yahoo! Finance's list also included fast-food establishments without locations in Jersey. Maybe that's a good thing?

Jack in the Box is a very popular chain with over 2,000 locations nationwide, none of which are in New Jersey.

This burger joint has slid in quality over the years, according to reviewers.
