A joke with the same tone but different meanings.

A few days ago, I went to a remote town on business. Because I often use my mobile phone, I quickly notified the arrears. There happened to be a mobile phone recharge card vendor by the roadside. In case of a savior, I quickly bought a prepaid card from 50 yuan, which is the kind of card that can get the password by scraping off the coating. I was dumbfounded when I saw it. I saw that it said: thank you for your patronage! Damn, I bought a prepaid card, not a scratch card! Pit dad!
