(My cousin who’s working in China calls me.)
Cousin: “Hey, cuz, my debit card doesn’t work in China. Could you please buy me a ticket to fly back from Hong Kong to Singapore and I’ll pay you back later?”
Me: “Sure, just give me your passport number.”
(Since everybody calls him by his English name, I buy a ticket for Jon [Surname] without thinking about it. On the day of his flight, I get a frantic call from the Hong Kong airport.)
Cousin: “I’m having a problem checking in. My ticket says Jon [Surname].”
Me: “So?”
Cousin: “My passport says [Surname] [Chinese name].”
Me: “Dude, how was I supposed to know Jon isn’t your legal name? I didn’t even know your Chinese name!”
(Fortunately, he managed to convince the airline staff that he was the same person, and at least the passport number matched.)
