I bet if you felt better, you wouldn't have let the woman get to you. Things always bother you more when you don't feel well and patience is at a low.
I run into people like that too, and I just smile and say I have to go. I don't bother to keep listening or talking to them because they're just very uneducated about the breed, and their opinions don't matter to me anyway because I don't even know them.
I hope you feel better soon!
