This is too intelligent for its own good. Early snippet:

… I opened the door and caused a stunningly beautiful girl to fall off a stepladder. “Euphemism!” she said. I swear to God she said “Euphemism.”
“Are you okay?” I asked. She was. She was holding two big yellow letters. I looked up at our sign. It was missing two big yellow letters.
“What do you think you’re doing?” I asked. I am bad at sounding threatening, but she was like 5’4, maybe 5’5, and also lying on the ground looking very ashamed, and so putting menace into my voice was easier than usual.
“Kabbalah,” she said.
I looked up at the sign again. It read CASH OR GOD
“It’s a kabbalistic protest,” she said faintly. “Against a society that thinks…”
“You’re not a kabbalist. If you were a kabbalist, you’d have more respect! You can’t just go removing letters from signs like that! Matthew 5:18: ‘Verily I say unto you, not a single letter, nor even a stroke of a letter, shall be removed until all is fulfilled.’”
“Oh, you want to go there?” She caught her breath and stood back up. “Matthew 16:4: ‘This evil and adulterous generation wants a sign, but no sign shall be given to it.’”
I blinked. Maybe she was a kabbalist.
“But,” I said, “By removing the letter L, you make “God” out of “gold”. But the warning against idolatry in Exodus 20:23 says ‘You shall not make a god out of gold.’”
“But,” said the girl, “Exodus 25 says that you shall take gold and turn it unto the Lord.”
Now I was annoyed.
“You have taken an L and an F,” I said. “But if you map the Latin alphabet to Hebrew gematria, L and F sum to twenty-six. The Tetragrammaton also has a gematria value of twenty six. So taking an L and an F is mystically equivalent to taking the Name of God. But the Third Commandment is ‘You shall not take the Name of God in vain.’”
“But the sound of L and F together,” she said, “is ‘aleph’, and aleph is silent and represents nothingness. So I have taken nothing.”
I heard the whine of a siren.
“Tell it to the cops,” I said. …

It wanders into more science fictional territory.
