Summary
This is a copypaste from 2ch that gave birth to a few popular tags on pixiv. In Japanese, there were a couple of puns poking fun at the formalspeak.
Rough Translation
Shop Worker: "Would you happen to have this shop's point card?"
I: "Wut!"
SW: "Would you happen to have this shop's point card?"
I: "...I wouldn't know about that."
SW: "Wut!"
I: "What."
SW: "I suppose you don't have one yet."
I: "Wut!"
SW: "What."
I: "Does it transform?"
SW: "What does?"
I: "That card of yours."
SW: "Ah. Well, if you are using it, it goes a rank up and the card will change."
I: "Woot that's cool."
SW: "Do you want to use it then? It's free."
I: "Won't it rot?"
SW: "Wut!"
I: "What."
SW: "Ah, you mean its expiration date? That would be a year since you last used it."
I: "WTF that's scary!"
SW: "Just come here every so often, and it should stay the same, like having an infinite expiry date."
I: "WTF that's scary too!"
SW: "Wut!"
I: "Wut!"

SW: "I suppose it hasn't turned into omochi yet."
I: "Wut!"
SW: "What."
I: "Does it transform?"
SW: "What does?"
I: "That card of yours."
SW: "Ah. Well, if you are using it, it goes a rank up and the card will change."
I: "Woot that's cool."
