A cafe with robots like seen at 3:17 wouldn't really work in the west. People are not considerate enough. The robot servants will be broken, stolen or the operators insulted for their disability. People can be rude. However, the idea behind it is awesome and I like it. And this should be researched a bit more.
Some of these humanoid robots are merely advanced animatronics without a useful function. Others are industrial machines. Until they are combined, there is no real economic purpose for human lifelike appearance. Meanwhile people can be employed and earn money for their families!
