Crazy Cashier

I had quite possibly the most strange encounter with a cashier I have ever had.

Dan and I made a run to Meijer last night. As I put my groceries on the conveyor belt, the cashier was muttering something under her breath. I couldn't make it out, so I said, "I'm sorry. Were you saying something to me?" She looked really irritated. She said, "What?" I told her how this was one of my first times at this Meijer. "Did I do anything wrong?" I said.

Her response was bizarre: "Do you have a guilty conscience about something?" (Enter Twilight Zone music here.)

Huh?

"I'm sorry? Look, I was just asking if I'm doing things correctly." I was a bit confused at this point and considered that my cashier may not be working with a full deck.

"You're fine." she said. But her body language was telling me otherwise.

I should have stopped there, but I'm a glutton for punishment and asked if I could purchase Aurora trash stickers. She didn't know what trash stickers were. "I'm not from here," she offered.

No, no you're not. Tell the mother ship hello from Earth.
