5. Burger King
A while back, Burger King’s burgers could have easily been considered tasty enough to earn them the “king” status. It is unfortunate that today’s Burger King is nowhere close to the establishment it once was. Have folks at Burger King given up their glory together? Did something change from their original recipes? Something is rotten in the King’s kingdom, and it needs to be changed fast.

Take this burger pictured above, for example, one can clearly tell that they are no longer interested in returning customers. Lucky for them, however, 33% of their customers would still consider putting up with their changed recipes for the second time. Considering that the king stands at position five, you wouldn’t like to imagine who tops the list, do you?
