Bob Wilson owns and operates Flashdance Skating Rink. Last Monday afternoon, he had rented the rink out for a birthday party that was cancelled at the last minute due to a flu epidemic that had sickened three-fourths of the children who were invited. While Wilson kept the deposit, he did not get the skate rental fees or the snack food money he had anticipated from the rental. Wilson lost money as a result of the ________ characteristic of services.
