It is inconsiderate cancel a reservation at the last minute.
Darryl made a reservation at a restaurant, with an elaborate plan in place to propose to his girlfriend, but he and his girlfriend are now in a fight.
Darryl has to decide whether to cancel the reservation or not.
Darryl called the restaurant as soon as he suspected that he may not be able to execute his plan, and that the reservation may not be necessary.
Darryl waits, but it doesn't work out, so he cancels the reservation and the plan on the day he was supposed to carry it out.
The restaurant was able to accommodate him by setting the plans on hold, so that even if he didn't make the reservation there would be no cost.
The restaurant had already ordered special supplies and had prepared their staff for the event, so they needed to charge a fee for the late cancellation.
