A conversation Dad had yesterday:
HSBC Lady: Ok, now I’ve taken all of the details I’ll need to call you back for security reasons
HSBC Lady: What’s your number?
Dad: Hang on, what’s the point of that? If I were trying to con you, I’d just give you this number! Haven’t you got it on your system somewhere?
HSBC Lady: Oh, probably
As long as they know what they’re doing.
