I was in the Express Lane at the store quietly fuming. Completely ignoring the sign, the woman ahead of me had slipped into the check-out line pushing a cart piled high with groceries. Imagine my delight when the cashier beckoned the woman to come forward, looked into the cart and asked sweetly, "So, which ten items would you like to buy?"
One of my pet peeves. If I'm standing behind someone waaaay over the 10, I count loudly enough for them to hear while they are taking the items out of the basket. If they don't like it, tough apples.
If they have Hell's Angel colors on, discretion prevails.
