Robot waiters get fired after disastrous performance

If the humans ain't broke, don't replace them with robots. Otherwise, your whole restaurant will itself be -- you guessed it -- broke. In a rather damning display of the limitations of technology, a fleet of useless robots meant to replace human servers have caused the demise of two restaurants in China. As it turns out, the answer to the question, "What can't robots do?" is actually, "a lot." Initially, Chinese restaurant chain Heweilai bought a whole staff's worth of automatons to wait on its patrons in three locations.
