Please tell me if I'm BU, or if this is legitimately a bit grim: a male colleague of mine, relatively senior, has taken to just wandering about the office in his bare feet. He sheds his loafers the minute he gets in and then that's it for the day. I can't put my finger on what exactly about this makes me a bit grossed out, but for some reason I just don't like it ha! He wanders past my desk and all I can see are his hairy toes 
For context, we work in financial services so it's not as though the office environment is super chilled and casual.
