Ah yes, these things. I have seen/used these in hotels here, like the Intercontinental and Shangri-la have them. To be honest, it didn’t really hit me that they were some Nip technology thing, I just thought it was a ‘posh hotel’ thing. Though it shouldn’t surprise me that they are Japanese technology, everything good here is, which I continually mock the Chinese for, because obviously they hate the Japanese.
When I was living in an apartment block here, we had some new Mitsubishi lifts installed. Some 60 year old neighbour bloke got in the lift and pressed a higher floor when it was on the way down, then started going ‘gan ma?’ (what’s it doing?) because it wouldn’t go up. I said to him “Japanese technology. Too advanced for you Chinese to operate.” He got really angry and started hitting the buttons and swearing. So I did the ‘Chinky eyes’ thing to him as I got off at the ground floor and watched as he fumed.
