Ok so I produced something for someone outside my department, who I've never met before. It was something totally outside my remit and not my responsibility to provide but I had the ability to do it so I thought I would do her a favour.
I sent the stuff in an email, I know she has read it because all my emails automatically have read receipts on them, and she hasn't even acknowledged I've sent the stuff, no even a one-worder saying 'Thanks'.
AIBU to think that's a bit rude when I needn't have bothered by arse to help her out?
