Because the dude answering the phone has a non-zero probability of being completely stoned off his ass. This is not theoretical. I am sad that we didn't record the worst one we ever had--it would have made for the absolute best YouTube video even though everyone would have been saying "That's so fake."

Phone orders are very error prone. Online orders help both sides of the equation. The customer knows exactly what they are getting and can verify it; the restaurant can say "We're happy to comp you for X because we're nice people, BUT this is the receipt THAT YOU ACKNOWLEDGED saying what you actually ordered."
