we too have had a encounter with the same dogs. at the time the dogs were also running out in the parking lot when my girlfriend decided to talk to this woman. after confronting her about the dogs, we continued to do our shopping when the woman came in and found us in the store to continue to yell at US!!!!!!!!!!!!!
saying that we were being rude and to mind our own bussiness.... i mean come on lady . she had me so floored and speachless. i have been waiting to see her again.
i do beleive you did the right thing, and i would have done the same thing. my girlfriend whom happens to be a dog grommer here in town were completly beside ourselfs...
good luck
