I will never forget in Japan at one point, I went into this cafe type place that had… like it was a wall with pictures of food, you pushed a button near a picture, put in $ and got a ticket. It was by the Akihabara train? Anyways, I put in a 10,000 yen note since thats all the atm gave me (~$100) and got no change
I panicked thinking it doesn’t give change and I would need to buy 100 bucks worth of soba.
This was my spending money for the whole weekend (grad student staying in a capsule hostel after a conference, extended layover, very tight budget)
This random guy turned around and saw my paniked look and comes over, hits the button, and pulls out the change and hands it to me, bows, and goes back to eating.
He actually seemed annoyed when I tried to thank him…
