I love these sorts of stories.
My favourite one was from when I worked on cruise ships. One of the guests asked my colleague if the staff also slept on the ships or if we went home each night. My colleagues joked that we got took home by a helicopter each night and brought back in the morning. He genuinely thought the guest was playing along but turns out he was very wrong. The guest complained at the end of the cruise that the helicopter collecting and dropping off the staff had kept her up every night and that the company should consider other means to ferry the staff around.
Please tell me your stories? I'm having a crap day!
