Seriously??

So I'm at work and it's already 7pm. the time we close. A lady walks in to the store and I tell her ma'am I'm sorry but were closed. She says she only wants to get one thing and it will be really quick. Again I tell her sorry but we are closed and need to get everyone out of the store now so that we can clean up and go home on time.

To this she replies: " It's because I'm Jewish, that's why you won't let me get the item."

I reply " It has NOTHING to do with your religion, it's just time for us to close."

Seriously? How the heck am I supposed to know that she is Jewish? And even if I did it has nothing to do with what religion she is. Some people really don't make any sense to me.
