Today, after I got in to work, I left my handbag on my desk with some of my items out and went to say hello to a colleague who had come back from sick leave As I stepped away from my desk, another colleague went up to my desk and started chatting with us (she went up to my desk to be closer to us). She ten proceeded to eat her sandwich while standing right over my desk and personal belongings (including handbag) Crumbs fell on handbag and desk, and she didn't even bother apologizing or wiping them off. Would you find this behavior somewhat out of the ordinary? I didn't say anything to her but I had to wipe everything up afterwards and haven't been talking to her much today.
