I went to a ramen place in Tokyo and to order ramen you had to insert money and place your order via this machine. This felt like going back to the early 90s but in a way that we are definitely not used to in western countries. It had a very retro futuristic vibe!
I found that so curious in Tokyo, even some hole-in-the-wall food shops would use the ticket system when the attendant is standing right next to the ticketing machine!
But, it is ubiquitous over there.
Weirdest thing I saw over there was deep fried sparrows.
Or the garden shop I went into had a (poor thing) monkey in a large cage who jacked off furiously and threw it at me.
Oh Tokyo, from one extreme to the other!
