A woman I work with has a habit of commenting on other's people's food as they're eating - usually negatively and sometimes it's really off putting.
I think this started because, as someone with a lot of dietary restrictions, she is more aware of food anyway and she frequently comments on people eating things that are outside her coeliac/dairy limitations.
Today someone at work had bought a pork sandwich and she said "Ugh, how can you eat that? It smells like dead pig" and I snapped and asked if she'd meant to be so rude?
Now I know this is an MN classic line which is partly why I came out with it, but I now feel like I've been the rude one - so MN, AIBU?
