A lady picks up several items at a supermarket.
When she got up to the checkout, she learned that one of her items did not have a price tag on it.
Imagine her embarrassment when the checkout girl got on the intercom and boomed out for all the shop to hear, "Price check in lane three for Tampax Supersize."
That was bad enough, but somebody at the back of the store apparantly misunderstood the word Tampax for Thumbtacks.
In a business-like tone, a voice boomed back over the intercom,
"The kind you push in with your thumb or the kind you pound in with a hammer?"
