Episode at last year.
I went to eat Oconomi-yaki with 2 friends in that day.
Oconomi-yaki mean about
"Japanese pancake" or "Japanese pizza".
In other time,
we had eaten much economy-yaki.
When asked for the check,
I have gotten this receipt.
「領収書」(mean about "receipt")
hadn't so much as Japanese.
I got this in that day. ↓
It was normal receipt in that time.
Secret Code had been only last time around.
Who can know foods we had eaten by reading above secret code receipt?
