There's a new guy at work, he's been here for about a month, he sits opposite me and is driving me insane already. He is constantly sniffing...not just a little sniff but a really big sniff that you can hear in the back of his throat. When he started doing it I did ask him to go and blow his nose and he said why, at which point I told him that he was constantly sniffing and it was annoying. Since then, he continues to do it but what he seems to think is 'stealth sniffing'. It isn't and I'm close to breaking point with it, it's really disgusting.
It's annoying others too but they are too scared to say something. He is not liked within the company for other reasons too and I'm worried that that is what is causing my extra annoyance with him...because I know he's an idiot anyway and the sniffing is the icing on the cake.
AIBU to tell him to stop again? Or should I just go to his boss and say something? I work very closely with his boss and could just make a passing comment that his sniffing is driving me and others insane rather than make a big deal of it.
