Maybe she was afraid she would die before she got to the front of the line. I had one of those yesterday. I collected a shopping cart that was left in the middle of the parking lot (one with a little car built in for kids). As I walked to the door a woman tried to cut me off but the car was in the way. She was all huffy like I was somehow wrong just for living. Inside I put the cart on the side and got a regular one. She was still huffing at me. Go figure.
