Where is the announcement probably taking place?

Ladies and gentlemen, may I have your attention please? Because diners don’t always show up for their reservations, we occasionally accept more reservations than the tables we can accommodate. This procedure allows us to maximize the number of tables that we fill. Usually, there are enough tables for everyone, but on very rare occasions we cannot seat all of the diners with confirmed reservations. That is unfortunately the case tonight. Are there any volunteers in the waiting room who would be willing to wait in exchange for a $75 Chez Pierre gift certificate?
