Intrepid and numb to fatigue, robots have come for human jobs before. Just ask fighter pilots, autoworkers and Wal-Mart checkout clerks.
Now, in Asia at least, robots are encroaching on yet another occupation: waiting tables.
The trend is official. In the past three years alone, robot food servers have appeared in Japan, South Korea, Hong Kong and mainland China. The latest restaurant to employ robo-waiters, a Japanese-themed sushi-and-barbecue eatery in Bangkok, has even fitted its bots with samurai plating and prop swords.
