They say the key to being a successful business is to do one thing and do it well. Some businesses try to be everything to everybody and it usually doesn't work out. Other businesses think they can crack the code of success by combining two genius business ideas into one and they're usually two businesses that should have never ever crossed paths or partnered up with each other. You know, Like a liquor and gun store. Or a Chinese food delivery company that also offers a plumbing services. Anyway, these are some pretty hilarious combination business FAILs.
