"I think we've already established that haven't we?"

A woman comes in at about 5:30 a.m. and I say, "Good morning, how are you?" She glares at me for a few seconds and says, "Okay, I guess, not that it's any of your business."

She heads to the back, goes into the bathroom for awhile, comes back out, gets some coffee and brings it to the register. Out of habit, as I am ringing her up, I say, "So how is your morning?"

She shoots me a dirty look and says, "I think we've already established that haven't we?"

"Well you never know," I say. "That was about ten minutes ago, I thought the situation could have changed while you were in the bathroom."

I get another dirty look, but no response.
