Thank you (to the guest who will remain nameless for now) for not honoring your reservation of 18 people tonight. We really didn't need those 5 tables and that server's entire section. Said team member really appreciates not being able to make rent next month for taking away 20% of one weeks income.
This note is to make more people aware of how hard it hits restaurants when you make multiple reservations and don't honor them or especially in this case when you make a large reservation and don't honor it. This is $$$$ of dollars of lost revenue and a team member who wasted an entire night trying to come in.
and in a comment:
We called and left message that morning. A email confirmation was sent 24hrs prior. She didn't answer the phone until 20 min after she was supposed to be at restaurant and still wanted us to hold table. I told her either put up a cc or cancel, she canceled.
This is why restaurants ask for credit card numbers for reservations for large parties.
