Sure, it's a gimmick, but like any really good gimmick, this caught our attention, and is worth sharing. The sushi restaurant chain YO!Sushi has introduced a flying drone server at its flagship restaurant in London.

According to Yo!Sushi's YouTube channel, the gadget, called the "iTray," is made from a light-weight carbon fibre frame and is activated by four propellers "making it incredibly nippy." 

The drone reportedly can deliver sushi at speeds of up to 25 mph. In the video below, a waitress oversees the drone delivery through a real-time video that is viewable on her iPad. So her job appears to be safe, at least for now. 

One question remains: would you tip this drone over 15 percent?
