Anybody ever had this issue?

A lady outside of the shop I was about to walk in to stopped me to talk about my baby, assuming she knew as she obviously saw my bump (because I have no idea who she is) - and whilst she was talking to me she was blowing her cigarette smoke right in my face and all over me. I had to stop her and tell her she's making me feel sick and she's highly ignorant for her actions... Was this too rude or??
