Here is a gift bag, that I bought the other day. I was half asleep and buying a rice-ball from a convenience store on the way to work. As I was leaving, I thought to myself "Did I just see what I think I saw?"
What was that word written on it?
Yes, it's true. Somebody, in a moment of spite or silliness or ignorance chose the word "sewer" to decorate a gift bag. And nobody in the company, from the design department to the production department to the management, to the staff at the convenience store, thought "hmm, I wonder what that word means." When I bought the bag, I told the girl at the counter what it meant, and she seemed amused.
