A woman in the grocery store is fidgeting, but standing patiently in line when a new check-out register opens next to her. As she begins to move her cart to the new line, a shopper comes from one of the food aisles and pushes in front of her to check out. The woman says, "Oh, please, after you!" and stays where she is.
Which is the woman implying?

The other shopper shouldn't have done that; it was rude.
The other shopper should feel free to take her place in the line.
The other shopper should go to another check out.
The other shopper should have finished shopping before getting in line
