That clerk should have said something to the woman. There are times I appaulade clerks that have the gumption to speak up. For example when kids are running wild through a store.
I used to work retail. It is amazing the things people will do themselves and let their kids do in stores. And get mad at the sales clerks who call them on it. I lost count of how many times I had to tell people I was not a babysitter and they couldn't let their kids run wild in the store. I wonder if they ever realized that their threat to never come back to the sotre had us all hoping they wouldn't?
