I accidentally sent an email to the wrong, let's call her, Maureen.
The incorrect Maureen emailed back in a flurry, saying "Was this meant for me?! It's not grea GDPR" 
She wasn't joking. She isn't the type to 'joke'.
AIBU to think this is ridiculous?
The email was a document about... hold onto your seats... How to work the coffee machine!
