Prevaricate
prevaricate (v.): to lie by omission or by not directly answering a question
“When Mr. William Faraday sat down to write his memoirs after fifty-eight years of blameless inactivity he found the work of inscribing the history of his life almost as tedious as living it had been, and so, possessing a natural invention coupled with a gift for locating the easier path, he began to prevaricate a little upon the second page, working his way up to downright lying on the sixth and subsequent folios.” ― Margery Allingham, Dancers in Mourning
Sounds like: free berry gate
Someone's suing the pick-your-own farm for their prevaricating. There's a gate there with a sign that says "free berry gate" and if you walk through it you see a patch where you can supposedly pick as many berries as you want for free. It's true, the berries are free, but you only find out when you're leaving that you have to pay an exorbitant "gate exit" fee that means the berries actually end up being super expensive.
