A young lady is buying a box

A young lady is buying a box of tampons in the store.

They are missing the UPC and won’t ring up.

The cashier asks his co-worker to go and check the price of Tampax.

Do you mean the kind you push in or the kind you hammer in?

Everyone including the cashier is shocked: What?

You said to check the price of thumb tacks. I am asking whether you mean the kind of thumb tacks you push in or the kind you hammer in?

You should have seen the face of the young lady who wanted to buy these tampons.
