It depends on how advanced the robot is as far as features and ability, and how early you choose to adopt the technology. Robot waiters in current use in various countries have reportedly cost anywhere from $30,000 - $100,000 or more. Modern robots should fall in price as they become replaced by newer, more expensive (and advanced) models.

The amount a person should compliment a waiter will depend on how gratuitous they have been overall. It is considered proper to compliment the waiter whenever they have provided exceptional service.
What makes a robot is A.I.( artificial intelligence) if you have a computer on wheels it's not a robot a robot is a electronic device that can do multiple tasks, a robot that rolls isn't a robot it has to do multiple tasks like my robot shamrock 17 it is real it glides,fights,rolls, and can be switched to remote controlled or free roaming so pretty much it has to do at least two tasks.
