I work in HR and around a year or so ago I was dealing with a query from a young girl, a teacher about some tech issues she was having with her payslip. I went out of my way to be helpful, but she was so rude back to me and her responses were very blunt, once I’d solved the query for her she didn’t even say thank you!! Anyway, yesterday whilst I was at work I spotted another email from her about the same thing and shock horror she was already complaining about this that and the other…. So I just deleted it hahaha
