On over-estimating the intelligence of the person at the other end of the phone
This exchange – part of a conversation with a call centre belonging to a well-known company - is 100 per cent genuine, and what follows left me unable to speak for at least half an hour:
Me: "Could you send confirmation to my email address?"
Call centre: "Sure – ready for it now"
Me: "My first name dot my last name at gmail dot com"
Them: "Cool! How did you get that?"
Sometimes, I despair for the future of the human race
