Real phone conversation from today:
"Hi, XYZ Restaurant. How can I help you ?"
"Yes, do you take reservations ?"
"What, you mean like for today ?"
"Actually, for Mother's Day."
"Welllll....We tried having reservations at Easter. But there were so many people showing up that people with reservations didn't get seated. Total disaster. We won't do that again. So yeah, we don't have reservations on Mother's Day. But you can still show up."
