Last night I'm in the grocery store picking up a few things for dinner.
It's an unusually busy time on a Sunday and due to the rain and forecast bad weather for what-is-now-today the place is packed with people in the aisles, but surprisingly few people in the checkout lanes.
I realize I have a few too many items for the express lane (10 or less; I have 12) so I go to the next available lane, find the separator, place it, and start putting my items on the belt.
Two bags of chips, box of brownies (chocolate therapy helps my migraines, leave me alone) etc.
The cashier rings up the remains of the order of the woman in front of me.
She picks up the order separator plastic piece, puts it aside and, before I realize what she's doing she checks my two bags of chips in on the other customer's order.
I manage to stop her as she's checking through my brownies.
Me: "Excuse me. Those are mine, as are the chips."
Other customer: "Yes those aren't mine, they're his."
She looks at the belt, my chips, the brownies in her hand, and looks indecisive. She voids the chips off OC's order, puts the chips and brownies at the back of my pile of product...
and proceeds to take the next two items on my pile of items and rings them up on the other customer's order!!
The cashier takes the two items off, puts them at the back of my pile, picks up one of my bags of chips again (because they were closest to her to reach again) and rings them through again.
At this point, OC and I look at each other and shared a combined look of "I'm so sorry/can you believe this" when we turned to the cashier and managed to separately say
Me: "The chips are mine"
OC: "My shopping is done, please give me my total"
Cashier rolls her eyes as if we're being the utmost ignorant idiots to her, with an exasperated sigh removes the chips once more "Your total is blah blah..."
