As the a restaurant manager who has looked at the date of an event, looked at the actual date, then looked at the date of the event again, looked at the sheet he gave the kitchen, looked at the extra servers on the schedule who were about to come in, looked back at the date, looked back at the email, realized that its the 25th and not the 18th, then had to go into the kitchen where several people are prepping for that event and have to lie to everyone “hey, they had to cancel and move it to next week. Don’t worry we can just do whatever with the food, they understand and are basically paying twice”
